Nursing Elites

1. The healthcare provider should utilize data about which of the following to provide information about the nutritional status of a client being evaluated for malnutrition?

• A. triceps skinfold measurement
• B. fasting blood glucose level
• C. hemoglobin A1c level
• D. serum lipid profile results

Correct answer: A

Rationale: Objective anthropometric measurements such as triceps skinfold and mid-arm circumference (MAC), along with weight, are usually used to diagnose malnutrition. Triceps skinfold measurement specifically helps assess body fat and muscle mass, providing valuable information about the client's nutritional status. Fasting blood glucose level, hemoglobin A1c level, and serum lipid profile results are important tests in assessing different aspects of health such as diabetes management and cardiovascular risk, but they are not specific indicators of malnutrition.

2. 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.

3. While performing wound care to a donor skin graft site, the nurse notes some scabbing at the edges and a black collection of blood. What is the nurse's next action?

• A. Leave the scabbed area alone and apply extra ointment
• B. Notify the physician
• C. Gently remove the debris and re-dress the wound
• D. Apply skin softening lotion for 3 hours and then re-dress

Correct answer: C

Rationale: When the nurse notes scabbing at the edges and a black collection of blood, it indicates the presence of debris that needs to be addressed. Leaving the scabbed area alone and applying extra ointment may not address the underlying issue and could lead to complications. Notifying the physician is important in some cases, but immediate action is required to prevent infection in this situation. Gently removing the debris and re-dressing the wound is the correct course of action to promote healing and prevent complications.

4. The client is taking Antabuse and should avoid eating foods that may trigger a disulfiram reaction. The nurse should instruct the client to avoid:

• A. Peanuts, dates, raisins
• B. Figs, chocolate, eggplant
• C. Pickles, salad with vinaigrette dressing, beef
• D. Milk, cottage cheese, ice cream

Correct answer: C

Rationale: The client taking Antabuse should avoid foods that contain alcohol or vinegar as they can trigger a disulfiram reaction. Pickles and vinaigrette dressing often contain vinegar, which the client should avoid. Beef is safe to consume. Choices A, B, and D do not contain alcohol or vinegar, so they are allowed for the client taking Antabuse.

5. 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.
