RN NCLEX Practice Test Questions
Extract:
Question 1 of 5
Which of the following serum laboratory values would the nurse monitor during gentamicin therapy?
Correct Answer: A
Rationale: A common side effect of gentamicin is nephrotoxicity. The serum laboratory test that best reflects kidney function is serum creatinine.
Question 2 of 5
The nurse is teaching a 10-year-old insulin-dependent diabetic how to administer insulin. Which one of the following steps must be taught for insulin administration?
Correct Answer: B
Rationale: Sites for injection need to be rotated, including abdominal sites, to enhance insulin absorption. The pinch technique is the most effective method for obtaining skin tightness to allow easy entrance of the needle to subcutaneous tissues. Massaging the site of injection facilitates absorption of the insulin. Changing the needle will break the sterility of the system. It has become acceptable practice to reuse disposable needles and syringes for 3-7 days.
Question 3 of 5
A client with a history of Addison's disease is admitted with complaints of nausea and vomiting. The nurse should expect the client to have:
Correct Answer: A
Rationale: Addison's disease causes adrenal insufficiency, reducing aldosterone, which leads to hyperkalemia due to impaired potassium excretion.
Question 4 of 5
The nurse is preparing a client with an axillopopliteal bypass graft for discharge. The client should be taught to avoid:
Correct Answer: C
Rationale: Clients with an axillopopliteal bypass graft should avoid prolonged sitting in a straight chair, as it can compress the graft and impair blood flow. Reclining, supine, or Sim’s positions are less likely to compromise the graft.
Question 5 of 5
The nurse is preparing to administer a dose of enoxaparin (Lovenox) to a client. Which injection site is most appropriate?
Correct Answer: D
Rationale: Enoxaparin, a low-molecular-weight heparin, is administered subcutaneously in the abdomen, 2 inches from the umbilicus, to ensure consistent absorption and minimize bruising. Muscle injections are inappropriate.
