Which lab test is used to assess renal function?
- A. Check blood glucose levels
- B. Monitor serum creatinine
- C. Monitor BUN
- D. Check electrolyte levels
Correct Answer: B
Rationale: The correct answer is B: Monitor serum creatinine. Serum creatinine is a key indicator of renal function as it reflects the glomerular filtration rate. An increase in serum creatinine levels indicates impaired kidney function. Checking blood glucose levels (choice A) is not specific to assessing renal function but is used to diagnose diabetes. Monitoring BUN (choice C) is important but not as specific as serum creatinine in assessing renal function. Checking electrolyte levels (choice D) is essential in assessing kidney function but is not as specific as monitoring serum creatinine.

A healthcare professional is reviewing the laboratory data of a client who has diabetes mellitus. Which of the following laboratory tests is an indicator of long-term disease management?
- A. Postprandial blood glucose
- B. Glycosylated hemoglobin (HbA1c)
- C. Glucose tolerance test
- D. Fasting blood glucose
Correct Answer: B
Rationale: Glycosylated hemoglobin (HbA1c) is the most accurate test for long-term management of blood glucose levels in individuals with diabetes mellitus. HbA1c reflects average blood glucose levels over the past 2-3 months, providing valuable information on the effectiveness of treatment and disease control. Postprandial blood glucose, glucose tolerance test, and fasting blood glucose are essential for monitoring blood glucose levels at specific times but do not offer the same insight into long-term disease management as HbA1c.
A client with asthma is being taught how to use a peak flow meter by a nurse. Which of the following instructions should the nurse include?
- A. Blow as hard as possible into the mouthpiece.
- B. Exhale quickly and forcefully after taking a deep breath.
- C. Inhale as deeply as possible and then blow into the mouthpiece.
- D. Take a deep breath and hold it for 5 seconds before exhaling.
Correct Answer: B
Rationale: The correct answer is B because the client should exhale quickly and forcefully into the peak flow meter after taking a deep breath to measure peak expiratory flow. Choice A is incorrect as blowing as hard as possible may not provide an accurate reading. Choice C is incorrect because inhaling deeply before blowing can affect the results. Choice D is incorrect as holding the breath before exhaling is not part of using a peak flow meter.
How should a healthcare professional monitor for infection in a patient with a central line?
- A. Check the central line dressing daily
- B. Monitor for signs of redness
- C. Check for abnormal breath sounds
- D. Monitor temperature
Correct Answer: A
Rationale: Correct answer: A. Checking the central line dressing daily is crucial to monitor for signs of infection around the insertion site. This practice helps in early detection of any changes such as redness, swelling, or discharge, which are indicators of a potential infection. Monitoring for signs of redness (choice B) is limited as redness alone may not always indicate an infection; other symptoms like discharge and tenderness should also be observed. Checking for abnormal breath sounds (choice C) is not directly related to monitoring central line infections. Monitoring temperature (choice D) is important for detecting systemic signs of infection but may not specifically indicate an infection related to the central line site.
A client is receiving a new prescription for enoxaparin. Which of the following instructions should the nurse include?
- A. Rub the injection site after administration.
- B. Pinch the skin while administering the injection.
- C. Aspirate before administering the medication.
- D. Avoid taking aspirin while using this medication.
Correct Answer: D
Rationale: The correct answer is D: 'Avoid taking aspirin while using this medication.' Enoxaparin is an anticoagulant medication, and taking aspirin concurrently can increase the risk of bleeding. Choices A, B, and C are incorrect. A nurse should not instruct the client to rub the injection site after administration as it may cause irritation. Pinching the skin while administering the injection is not recommended for enoxaparin injections. Aspirating before administering the medication is also unnecessary as enoxaparin is administered subcutaneously, not intramuscularly.
A nurse is caring for a client who has deep vein thrombosis. Which of the following instructions should the nurse include in the plan of care?
- A. Limit the client's fluid intake to 1500 mL per day.
- B. Avoid massaging the affected extremity to relieve pain.
- C. Do not apply cold packs to the client's affected extremity.
- D. Elevate the client's affected extremity when in bed.
Correct Answer: D
Rationale: The correct answer is to elevate the client's affected extremity when in bed. Elevating the extremity helps to reduce swelling and improve venous return in clients with DVT. Limiting fluid intake to 1500 mL per day (Choice A) is not directly related to managing DVT. Massaging the affected extremity (Choice B) can dislodge a clot and lead to serious complications. Applying cold packs (Choice C) can vasoconstrict blood vessels, potentially worsening the condition by reducing blood flow.
