Nursing Elites

1. The physician wants to know if a client is tolerating their total parenteral nutrition. Which of the following laboratory tests is likely to be ordered?

• A. triglyceride level
• B. liver function tests
• C. a glucose tolerance test
• D. a complete blood count

Correct answer: B

Rationale: The liver is crucial in processing nutrients and medications received through total parenteral nutrition. Liver function tests assess various enzymes produced by the liver, including prothrombin time/partial prothrombin time, serum glutamic oxaloacetic and pyruvic transaminases, gamma glutamyl transpeptidase, albumin, and alkaline phosphatase. Monitoring these enzymes can help determine if the liver is functioning properly to metabolize the nutrients from TPN. Triglyceride levels (Choice A) primarily evaluate the body's ability to clear fats, not specifically related to TPN tolerance. A glucose tolerance test (Choice C) is used to diagnose diabetes by measuring blood glucose levels after ingesting a glucose-rich solution, not directly related to TPN tolerance. A complete blood count (Choice D) assesses blood components such as red blood cells, white blood cells, and platelets but does not provide specific information about TPN tolerance.

2. A 22-year-old patient in a mental health lock-down unit under suicide watch appears happy about being discharged. Which of the following is probably happening?

• A. The patient is excited about being around family again.
• B. The patient's suicide plan has probably progressed.
• C. The patient's plans for the future have been clarified.
• D. The patient's mood is improving.

Correct answer: B

Rationale: In this scenario, it is concerning that a patient under suicide watch is happy about being discharged as it may indicate that the patient's suicide plan has advanced. This change in behavior should be taken seriously as it can signal an increased risk of self-harm. Choices A, C, and D are less likely as the patient's happiness about discharge in this context is more indicative of a worsening situation rather than positive outcomes like being around family, clarifying future plans, or improving mood.

3. Which of the following arterial blood gas values indicates a patient may be experiencing a condition of metabolic acidosis?

• A. PaO2 90 mm Hg
• B. Bicarbonate 15 mEq/L
• C. CO2 47 mm Hg
• D. pH 7.34

Correct answer: B

Rationale: The correct answer is B: Bicarbonate 15 mEq/L. In metabolic acidosis, the bicarbonate levels are lower than normal. A bicarbonate value of 15 mEq/L indicates a deficit in the buffer system, contributing to the acidosis. Choices A, C, and D are incorrect. Choice A, PaO2 90 mm Hg, reflects oxygen partial pressure and is not directly related to metabolic acidosis. Choice C, CO2 47 mm Hg, represents carbon dioxide levels and is more indicative of respiratory status. Choice D, pH 7.34, falls within the normal range (7.35-7.45) and does not confirm metabolic acidosis.

4. Which dietary consideration is most important for the nurse to teach to a client with hypothyroidism?

• A. Increase carbohydrate intake
• B. Increase fluid intake
• C. Avoid shellfish
• D. Increase fiber

Correct answer: D

Rationale: The correct answer is to 'Increase fiber.' In hypothyroidism, clients often experience constipation due to decreased metabolic rate. Increasing fiber in the diet can help alleviate constipation. Choice A, 'Increase carbohydrate intake,' is incorrect as there is no specific need to increase carbohydrate intake in hypothyroidism. Choice B, 'Increase fluid intake,' is not directly related to managing hypothyroidism, although adequate hydration is generally important for overall health. Choice C, 'Avoid shellfish,' is commonly associated with hyperthyroidism due to its iodine content, not hypothyroidism.

5. A homeless person has been admitted to the medical unit and placed on airborne precautions for suspected active TB infection. The nurse will assess for these signs and symptoms (Select one that doesn't apply).

• A. Weight gain
• B. Fatigue
• C. Bloody sputum
• D. Diaphoresis during sleep

Correct answer: A

Rationale: The correct answer is 'Weight gain.' When assessing for signs and symptoms of active TB infection, weight loss is typically observed rather than weight gain. Other common signs and symptoms include fatigue, bloody sputum, and diaphoresis during sleep. Fatigue, bloody sputum, and diaphoresis during sleep are all associated with active TB infection. Weight gain is not typically seen in active TB; instead, patients usually experience weight loss due to the impact of the infection on their overall health.
