Correct Answer: D

Rationale: The correct answer is D, a heart rate of 160/min. A heart rate of 160/min in a newborn exceeds the normal range and could indicate potential issues that need further evaluation by the provider. Acrocyanosis (choice A) is a common finding in newborns and is not concerning. Vernix caseosa (choice B) is a white, cheesy substance found on newborn skin and is a normal finding. While a respiratory rate of 50/min (choice C) is slightly elevated, it is not as concerning as a high heart rate in a newborn.

Correct Answer: C

Rationale: The correct answer is lean beef because it is a good source of protein and essential nutrients. When providing dietary recommendations to clients with hypertension, it is important to focus on lean protein sources to promote a balanced diet. Bananas, although a healthy fruit, may not be the best choice due to their high potassium content, which can sometimes be a concern for individuals with hypertension. Whole grains are generally a good choice, but lean protein like beef is more suitable in this scenario. Canned soup often contains high levels of sodium, which is not recommended for individuals with hypertension.

Correct Answer: A

Rationale: The correct answer is A: Potassium 3.5 mEq/L. Digoxin can cause hypokalemia as an adverse effect. Monitoring potassium levels is crucial because low potassium levels can increase the risk of digoxin toxicity. Choices B, C, and D are incorrect as they are not directly associated with potential adverse effects of digoxin. Sodium levels are not typically affected by digoxin, calcium levels are not a primary concern with digoxin therapy, and magnesium levels are not the most important to monitor for digoxin adverse effects.

Correct Answer: B

Rationale: An elevated WBC count 48 hours postoperatively may indicate an infection and should be reported to the provider. Choice A, a heart rate of 90/min, is within normal limits and not a concerning finding postoperatively. Choice C, urinary output of 75 mL in the past 4 hours, may indicate decreased renal perfusion, but an elevated WBC count is a more urgent finding. Choice D, a temperature of 37.8°C (100°F), which is slightly elevated, could be indicative of the body's normal response to surgery and is not as alarming as an elevated WBC count.

Correct Answer: C

Rationale: Administering anticoagulants as prescribed is a crucial intervention for clients with pulmonary embolism to prevent further clot formation. Encouraging the client to ambulate frequently may dislodge the clot and lead to worsening symptoms. Placing the client in a prone position can compromise respiratory function. Initiating seizure precautions is not directly related to the management of pulmonary embolism.
