Nursing Elites

1. After 2 months of tuberculosis (TB) treatment with isoniazid (INH), rifampin (Rifadin), pyrazinamide (PZA), and ethambutol, a patient continues to have positive sputum smears for acid-fast bacilli (AFB). Which action should the nurse take next?

• A. Teach about drug-resistant TB treatment
• B. Ask the patient whether medications have been taken as directed
• C. Schedule the patient for directly observed therapy three times weekly
• D. Discuss with the healthcare provider the need for the patient to use an injectable antibiotic

Correct answer: B

Rationale: The first action should be to determine whether the patient has been compliant with drug therapy because negative sputum smears would be expected if the TB bacillus is susceptible to the medications and if the medications have been taken correctly. Assessment is the first step in the nursing process. Depending on whether the patient has been compliant or not, different medications or directly observed therapy may be indicated. The other options are interventions based on assumptions until an assessment has been completed. Teaching about drug-resistant TB treatment (Choice A) is premature without knowing the current medication compliance status. Scheduling directly observed therapy (Choice C) assumes non-compliance without confirming it first. Discussing the need for an injectable antibiotic (Choice D) is premature and not necessarily indicated without assessing the current medication adherence.

2. Clinical manifestations of asthma include:

• A. Decreased expiratory time
• B. Increased peak expiratory flow
• C. Increased use of accessory muscles
• D. Increased oxygen saturation

Correct answer: C

Rationale: Clinical manifestations of asthma include increased use of accessory muscles, increased expiratory time, increased peak expiratory flow, and decreased oxygen saturation. Choice A, 'Decreased expiratory time,' is incorrect because asthma typically presents with increased expiratory time due to airway obstruction. Choice B, 'Increased peak expiratory flow,' is incorrect as asthma commonly leads to decreased peak expiratory flow due to airway constriction. Choice D, 'Increased oxygen saturation,' is incorrect because asthma exacerbations often result in decreased oxygen saturation levels.

3. How does shock typically progress?

• A. Compensated to hypotensive shock in hours and hypotensive shock to cardiac arrest in minutes
• B. Compensated to hypotensive shock in minutes and hypotensive shock to cardiac arrest in hours
• C. Hypotensive to compensated shock in hours and compensated shock to cardiac arrest in minutes
• D. Hypotensive to compensated shock in minutes and compensated shock to cardiac arrest in hours

Correct answer: A

Rationale: Shock typically progresses from a compensated state to hypotensive shock over a period of hours. In the compensated phase, the body is trying to maintain perfusion. It is crucial to identify and intervene during this phase to prevent progression to hypotensive shock, where blood pressure drops significantly. If not promptly managed, hypotensive shock can rapidly deteriorate into cardiac arrest in minutes due to inadequate perfusion to vital organs. Choices B, C, and D are incorrect as they do not follow the typical progression of shock stages as seen in clinical practice. Understanding the stages of shock and their timeframes is crucial for early recognition and appropriate intervention to prevent further deterioration.

4. A serum potassium level of 3.2 mEq/L (3.2 mmol/L) is reported for a patient with cirrhosis who has scheduled doses of spironolactone (Aldactone) and furosemide (Lasix) due. Which action should the nurse take?

• A. Administer both drugs.
• B. Administer the spironolactone.
• C. Withhold the spironolactone and administer the furosemide.
• D. Withhold both drugs until discussed with the healthcare provider.

Correct answer: B

Rationale: A serum potassium level of 3.2 mEq/L is low (hypokalemia), which can be concerning in a patient with cirrhosis who is already at risk for electrolyte imbalances. Spironolactone is a potassium-sparing diuretic that can help increase the patient's potassium level and correct the hypokalemia. Therefore, the appropriate action for the nurse to take in this scenario is to administer the spironolactone. Withholding the spironolactone could further lower the potassium level. Furosemide, on the other hand, is a loop diuretic that can lead to potassium loss and worsen hypokalemia; hence, it should be withheld until the nurse discusses the situation with the healthcare provider. While the healthcare provider should be informed about the low potassium value, immediate administration of spironolactone is necessary to address the hypokalemia in this patient population.

5. A thirty-five-year-old male has been an insulin-dependent diabetic for five years and now is unable to urinate. Which of the following would you most likely suspect?

• A. Atherosclerosis
• B. Diabetic nephropathy
• C. Autonomic neuropathy
• D. Somatic neuropathy

Correct answer: C

Rationale: In this case, the correct answer is autonomic neuropathy. Autonomic neuropathy affects the autonomic nerves, which control various bodily functions including the bladder. In diabetes, it can lead to bladder paralysis, resulting in symptoms like urgency to urinate and difficulty initiating urination. Atherosclerosis (choice A) is a condition involving the hardening and narrowing of arteries, not directly related to the inability to urinate in this context. Diabetic nephropathy (choice B) primarily affects the kidneys, leading to kidney damage, but does not typically cause urinary retention. Somatic neuropathy (choice D) involves damage to sensory nerves, not the autonomic nerves responsible for bladder control, making it less likely to be the cause of the urinary issue described in the question.
