1. Which of the following lab values indicates a patient on warfarin is at a therapeutic level?

Correct answer: C

Rationale: An INR of 2.5 indicates a therapeutic level for a patient on warfarin. The INR (International Normalized Ratio) is the most accurate way to monitor and adjust warfarin doses. An INR of 1.1 (Choice A) is below the therapeutic range, indicating a need for an increased dose. PT (Prothrombin Time) of 12 seconds (Choice B) is not specific for warfarin therapy monitoring. Platelet count (Choice D) is not directly related to monitoring warfarin therapy.

2. A nurse is reviewing the medical record of a client who is receiving gentamicin for a wound infection. Which of the following findings should the nurse report to the provider?

Correct answer: A

Rationale: An elevated BUN level indicates possible nephrotoxicity, which is a side effect of gentamicin and should be reported. Elevated serum creatinine and WBC count are not specifically related to gentamicin therapy. Normal serum glucose levels are also within the expected range.

3. A nurse is assessing a newborn's heart rate. Which of the following actions should the nurse take?

Correct answer: A

Rationale: Corrected Rationale: Auscultating the apical pulse and counting for one minute is the appropriate method to accurately measure a newborn's heart rate. The apical pulse is located at the point of maximum impulse (PMI), which is usually at the fourth or fifth intercostal space along the mid-clavicular line. This method allows for a precise assessment of the newborn's heart rate. Choice B, placing a sensor on the index finger, is incorrect because this method is more suitable for measuring oxygen saturation rather than heart rate. Choice C, heating the skin prior to placing the probe, is unnecessary for assessing heart rate and may lead to potential burns in newborns. Choice D, rechecking after 10 minutes, is not appropriate as immediate assessment and intervention may be required if an abnormal heart rate is detected in a newborn.

4. A nurse is caring for a client who is receiving chemotherapy. Which of the following findings should the nurse report to the provider?

Correct answer: B

Rationale: The correct answer is B. A weight gain of 1 kg (2.2 lb) in 24 hours is concerning as it indicates fluid retention, which can be a sign of complications in clients receiving chemotherapy. Rapid weight gain can be associated with conditions like fluid overload or electrolyte imbalances, which need prompt medical attention. Choices A, C, and D are not typically immediate concerns related to chemotherapy. Alopecia (choice A) is a common side effect of chemotherapy, a white blood cell count of 6,000/mm³ (choice C) falls within the normal range, and a temperature of 37.2°C (99°F) (choice D) is slightly elevated but not a critical finding in this context.

5. A nurse is providing discharge instructions for a client who has osteoporosis. Which of the following instructions should the nurse include to prevent injury?

Correct answer: A

Rationale: The correct answer is A: Perform weight-bearing exercises. Weight-bearing exercises are crucial for preventing bone density loss in clients with osteoporosis. These exercises help strengthen bones and reduce the risk of fractures. Option B, avoiding crossing the legs beyond the midline, is not directly related to preventing injury in osteoporosis. Option C, avoiding sitting in one position for prolonged periods, is important for preventing pressure ulcers but does not specifically address preventing injury in osteoporosis. Option D, splinting the affected area, is not a standard recommendation for preventing injury in osteoporosis.
