Correct Answer: B

Rationale: The correct answer is B. An apical pulse below 60/min indicates bradycardia, a potential sign of digoxin toxicity. The nurse should report this finding to the provider for further evaluation and possible adjustment of the digoxin dose. Choice A, a potassium level of 4.2 mEq/L, is within the normal range (3.5-5.0 mEq/L) and does not indicate toxicity. Choice C, a digoxin level of 1 ng/ml, is within the therapeutic range (0.5-2 ng/ml) and is not suggestive of toxicity. Choice D, constipation for 2 days, is not directly related to digoxin administration and would not require an immediate report to the provider.

Correct Answer: B

Rationale: A weight gain of 0.9 kg (2 lb) in 1 week is an indication of fluid retention, which is concerning in a client with preeclampsia. This can be a sign of worsening condition requiring immediate medical attention. High blood pressure (option A) is expected in preeclampsia, a urine output of 30 mL/hr (option C) is decreased but not as urgent as the weight gain in this scenario, and a respiratory rate of 16/min (option D) is within normal limits.

Correct Answer: D

Rationale: The correct answer is D: Hyperkalemia. In chronic kidney disease, there is decreased renal excretion of potassium, leading to elevated serum potassium levels. Hypokalemia (Choice A) is low potassium levels, which is the opposite finding in this scenario. Hypocalcemia (Choice B) is decreased calcium levels and is not directly related to chronic kidney disease or elevated potassium levels. Hypoglycemia (Choice C) is low blood sugar levels and is not typically associated with chronic kidney disease or high potassium levels.

Correct Answer: B

Rationale: The correct answer is B. Instructing the client to take levothyroxine in the morning is important to prevent insomnia, a common side effect of this medication. Choice A is incorrect as levothyroxine should be taken on an empty stomach. Choice C is inaccurate because weight loss, not weight gain, is a potential side effect of levothyroxine. Choice D is not necessary as clients do not need to avoid foods containing iodine while taking levothyroxine.

Correct Answer: D

Rationale: An irregularly shaped mole is a priority finding to report to the provider as it can be indicative of melanoma, a type of skin cancer. Melanoma is a serious condition that requires prompt evaluation and treatment. Raised nevus, macule, and vesicle are common skin findings that are typically benign and may not require immediate attention. Therefore, the irregularly shaped mole stands out as the priority due to its association with potential malignancy.
