Nursing Elites

1. A patient is hospitalized with active tuberculosis. The patient is receiving antitubercular drug therapy and is not responding to the medications. What do you suspect the patient is suffering from?

• A. Human immunodeficiency virus
• B. Drug-resistant tuberculosis
• C. Methicillin-resistant Staphylococcus aureus
• D. Vancomycin-resistant Staphylococcus aureus

Correct answer: B

Rationale: When a patient with active tuberculosis is not responding to antitubercular drug therapy, drug-resistant tuberculosis should be suspected. Drug-resistant tuberculosis occurs when the bacteria causing tuberculosis become resistant to the medications being used. Choices A, C, and D are incorrect because the scenario described does not align with HIV infection, methicillin-resistant Staphylococcus aureus, or vancomycin-resistant Staphylococcus aureus.

2. Which symptoms are typical of asthma?

• A. Chest pain; cough
• B. Diarrhea; wheezing
• C. Wheezing; dyspnea
• D. Tachypnea; constipation

Correct answer: C

Rationale: The correct answer is C: Wheezing and dyspnea are typical symptoms of asthma. Wheezing refers to a high-pitched whistling sound while breathing, and dyspnea is shortness of breath. These symptoms are classic signs of airway obstruction and inflammation seen in asthma. Choice A is incorrect as chest pain is not a typical symptom of asthma, though coughing can occur. Choice B is incorrect as diarrhea is not associated with asthma, while wheezing is a common symptom. Choice D is incorrect as tachypnea (rapid breathing) can occur in asthma, but constipation is not a typical symptom.

3. A patient's current medical condition is suggestive of impaired erythropoiesis. Which of the following laboratory studies would be most clinically relevant in diagnosing this health problem?

• A. White blood cell count with differential
• B. RBC, hemoglobin, and hematocrit
• C. INR and aPTT
• D. d-dimer and C-reactive protein

Correct answer: B

Rationale: In this scenario, where impaired erythropoiesis is suspected, the most clinically relevant laboratory studies would focus on red blood cell parameters. Therefore, assessing RBC count, hemoglobin levels, and hematocrit values would provide direct insights into erythropoiesis. Choices A, C, and D are not directly related to erythropoiesis assessment. White blood cell count with a differential is more indicative of immune response and infection. INR and aPTT are coagulation studies, while d-dimer and C-reactive protein levels are more associated with inflammation and thrombotic events.

4. What important point should the nurse emphasize about taking oral contraceptives consistently?

• A. Oral contraceptives must be taken at the same time each day to maintain consistent hormone levels and ensure effectiveness in preventing pregnancy.
• B. Oral contraceptives should be taken in the morning to avoid side effects at night.
• C. Oral contraceptives should be taken with food to enhance absorption.
• D. Oral contraceptives can be skipped occasionally without significant consequences.

Correct answer: A

Rationale: The correct answer is A. It is crucial for patients taking oral contraceptives to take them at the same time each day to maintain consistent hormone levels, which is essential for their effectiveness in preventing pregnancy. Choice B is incorrect as the timing of the medication is more about consistency than avoiding side effects at night. Choice C is incorrect as oral contraceptives do not necessarily need to be taken with food for absorption. Choice D is incorrect because skipping oral contraceptives occasionally can significantly reduce their effectiveness in preventing pregnancy.

5. Not realizing that its surface was hot, a woman has quickly withdrawn her hand from the surface of a bowl that she was removing from a microwave. Which phenomena has facilitated the rapid movement of her hand in response to the painful stimulus?

• A. Crossed-extensor reflex
• B. Flexor reflex
• C. Withdrawal reflex
• D. Stretch reflex

Correct answer: C

Rationale: The withdrawal reflex is a protective response that allows a person to quickly remove their hand from a painful stimulus.
