Correct Answer: B

Rationale: The correct answer is B: Halos around lights. Digoxin toxicity can cause visual disturbances like seeing halos around lights, which is a common symptom. This is due to its effect on the eyes. Poor appetite (choice A) is a common side effect but not specific to toxicity. Constipation (choice C) is not a typical sign of digoxin toxicity. Tachycardia (choice D) is more commonly associated with digoxin toxicity, but visual disturbances like halos around lights are more specific and should be explained to the patient.

Correct Answer: B

Rationale: The correct answer is B: Encourage ambulation and liberal fluid. Encouraging ambulation can help in the movement of kidney stones and alleviate pain. Liberal fluid intake helps in flushing out kidney stones and preventing further stone formation. Incorrect options: A: Administering prescribed nephrotoxic drugs can worsen kidney function and exacerbate the pain. C: Observing aseptic principles when changing intake is important for infection prevention but not directly related to pain management for renal calculi. D: Providing a comfortable position can offer temporary relief but does not address the underlying cause of kidney stone pain.

Correct Answer: B

Rationale: The correct answer is B: Positioning the patient on his or her side. This is essential for a lumbar puncture as it helps to open up the spinal spaces, making it easier and safer for the procedure. Positioning the patient on their side also helps prevent complications such as nerve damage or spinal fluid leakage. A: Administering enemas until clear is unnecessary and not directly related to preparing a patient for a lumbar puncture. C: Removing all metal jewelry is important to prevent interference with imaging studies, but it is not directly related to preparing for a lumbar puncture. D: Removing the patient’s dentures is not specifically required for a lumbar puncture procedure.

Correct Answer: B

Rationale: The correct answer is B: Hypotension. Glipizide is a sulfonylurea medication used to treat diabetes by lowering blood sugar levels. Hypotension, or low blood pressure, can be an adverse reaction as glipizide may cause vasodilation leading to a drop in blood pressure. Headache (choice A), constipation (choice C), and photosensitivity (choice D) are not common adverse reactions associated with glipizide use. Headache may occur due to other factors, constipation is more commonly associated with opioids, and photosensitivity is typically seen with certain antibiotics or NSAIDs.

Correct Answer: D

Rationale: The correct answer is D because a class V finding on a Pap test indicates severe dysplasia or carcinoma in situ, which requires further evaluation through a biopsy to confirm the presence of abnormal cells. This finding is not normal and necessitates immediate action for diagnosis and potential treatment. Choices A, B, and C are incorrect because they do not address the urgency and seriousness of a class V finding, which mandates prompt follow-up to rule out or confirm the presence of precancerous or cancerous cells.
