Practice Test Flashcards

A patient has taken an overdose of aspirin. Which of the following should a nurse most closely monitor for during acute management of this patient?

Answer: Onset of pulmonary edema

Aspirin (salicylate) overdose is a serious condition that can lead to various complications, including direct toxicity to the lungs. This toxicity can cause non-cardiogenic pulmonary edema, which is a life-threatening accumulation of fluid in the lungs. Monitoring for this acute respiratory complication is crucial during the management of aspirin overdose.

A nurse if reviewing a patient’s chart and notices that the patient suffers from conjunctivitis. Which of the following microorganisms is related to this condition?

Answer: Haemophilus aegyptius

Conjunctivitis, commonly known as 'pink eye,' is an inflammation of the conjunctiva. While various microorganisms can cause it, *Haemophilus aegyptius* is a well-known bacterial pathogen specifically associated with acute purulent conjunctivitis, especially in tropical regions. It is also linked to Brazilian purpuric fever.

A 24-year-old female is admitted to the ER for confusion. This patient has a history of a myeloma diagnosis, constipation, intense abdominal pain, and polyuria. Based on the presenting signs and symptoms, which of the following would you most likely suspect?

Answer: Hypercalcaemia

The patient's symptoms of confusion, constipation, intense abdominal pain, and polyuria, combined with a history of myeloma, are classic indicators of hypercalcemia. Multiple myeloma often causes bone destruction, leading to an excessive release of calcium into the bloodstream. This elevated calcium level can manifest with the described neurological, gastrointestinal, and renal symptoms.

A 50-year-old blind and deaf patient have been admitted to your floor. As the charge nurse, your primary responsibility for this patient is?

Answer: Provide a secure environment for the patient

For a patient who is both blind and deaf, their primary vulnerability is to their physical safety within an unfamiliar environment. As the charge nurse, the most immediate and critical responsibility is to provide a secure environment, minimizing hazards and ensuring the patient can navigate safely. While communication and informing staff are important, ensuring physical safety takes precedence.

A client with myocardial infarction is receiving tissue plasminogen activator, alteplase (Activase, tPA). While on the therapy, the nurse plans to prioritize which of the following?

Answer: Observe for signs of bleeding.

Tissue plasminogen activator (tPA), such as alteplase, is a potent thrombolytic agent designed to dissolve blood clots. Its mechanism of action carries a significant risk of bleeding, which can range from minor superficial bleeding to life-threatening hemorrhage. Therefore, closely observing for any signs of bleeding is the highest nursing priority during tPA therapy.

A nurse is reviewing a patient’s medication during shift change. Which of the following medication would be contraindicated if the patient were pregnant? Select all that apply:

Answer: Warfarin (Coumadin)

Warfarin is a known teratogen, meaning it can cause severe birth defects (fetal warfarin syndrome) when taken during pregnancy. Finasteride is an anti-androgen that can cause feminization of a male fetus, making it contraindicated for pregnant women or those who could become pregnant. Both medications pose significant risks to fetal development.

A 28-year-old male has been found wandering around in a confused pattern. The male is sweaty and pale. Which of the following tests is most likely to be performed first?

Answer: Blood sugar check

The symptoms of confusion, sweating, and pallor are classic signs of hypoglycemia, or low blood sugar. This condition can rapidly become life-threatening if not addressed promptly. A blood sugar check is a quick, non-invasive, and essential diagnostic test to confirm hypoglycemia and guide immediate treatment, making it the most likely first test performed.

A patient who has been diagnosed with vasospastic disorder (Raynaud’s disease) complains of cold and stiffness in the fingers. Which of the following descriptions is most likely to fit the patient?

Answer: A young woman.

Raynaud's disease (primary Raynaud's phenomenon) is a common vasospastic disorder characterized by episodic constriction of small blood vessels, typically in the fingers and toes, in response to cold or stress. It most frequently affects young women, often beginning between the ages of 15 and 30. Therefore, a young woman is the most likely demographic to fit this description.

An infant is brought to the clinic by his mother, who has noticed that he holds his head in an unusual position and always faces to one side. Which of the following is the most likely explanation?

Answer: Torticollis, with shortening of the sternocleidomastoid muscle.

Torticollis, also known as 'wry neck,' is a condition in infants where the head is tilted to one side and rotated to the opposite side due to the shortening or spasm of the sternocleidomastoid muscle. This muscle shortening causes the characteristic unusual head position and restricted range of motion. It is a common musculoskeletal issue in infants.

What does a level-of-evidence model use to evaluate the strength of a research study and its findings? Select all that apply.

Answer: Quality

Level-of-evidence models are frameworks used to evaluate the strength and reliability of research studies and their findings, guiding evidence-based practice. These models typically assess the **quality** of the study design and execution, the **quantity** of research on a topic, and the **consistency** of findings across multiple studies. These three criteria help determine the overall strength of the evidence.

What are the critiquing criteria used to judge the worth of a research study? Select all that apply.

Answer: Measures

Critiquing a research study involves a systematic and objective appraisal of its strengths and weaknesses to determine its worth and applicability. This process is guided by established **standards**, **measures**, **evaluation guides**, and specific **questions** that assess various aspects of the study, such as its methodology, ethical considerations, and the validity of its findings.

Which statement best describes qualitative research? Select all that apply.

Answer: Studies are conducted in natural settings.

Qualitative research is characterized by its focus on understanding complex phenomena within their natural settings, exploring subjective experiences, meanings, and perspectives. It often involves in-depth data collection from a smaller number of subjects, and while the design is systematic, the interpretation of rich, descriptive data is inherently subjective. This approach aims for deep understanding rather than statistical generalization.

What does a critique of a research study always include? Select all that apply.

Answer: Determining its strengths and weaknesses

A critique of a research study is a systematic and objective appraisal that involves carefully examining the study's strengths and weaknesses. It requires the application of critical reading skills to analyze the methodology, findings, and implications. The goal is to evaluate the study's rigor and validity, not to express personal opinions or simply research similar studies.

For which of the following research questions would qualitative methods be most appropriate?

Answer: What is the meaning of health for migrant farm-worker women?

Qualitative research aims to explore and understand subjective experiences, perceptions, and meanings. The question 'What is the meaning of health for migrant farm-worker women?' directly seeks to uncover the lived experiences and interpretations of a specific group, which is a hallmark of qualitative inquiry. The other options are quantitative, focusing on measurable outcomes or comparisons.

Which of the following phrases would be found in a report of a qualitative study?

Answer: “Subjects were asked to relate their perceptions of pain?”

Qualitative studies focus on understanding subjective experiences, perceptions, and meanings. Phrases like 'Subjects were asked to relate their perceptions of pain' indicate an approach that gathers rich, descriptive, and narrative data directly from participants about their personal experiences. This is characteristic of qualitative research, which seeks in-depth understanding rather than numerical measurement.

Which of the following phrases would be found in a report of a quantitative study?

Answer: “A convenience sample was chosen?”

Quantitative studies focus on collecting and analyzing numerical data to test hypotheses, establish relationships, and generalize findings. The phrase 'A convenience sample was chosen' refers to a non-probability sampling method used to select participants for quantitative data collection. This is a common practice in quantitative research where statistical analysis will be applied to the collected numbers.
