Correct Answer: C

Rationale: When caring for a client with bipolar disorder experiencing acute mania and having obtained a verbal prescription for restraints, the nurse must ensure to obtain a formal written prescription for restraint within 4 hours. This is crucial to maintain the safety and proper care of the client. Choices A, B, and D are incorrect because renewing the prescription every 8 hours, checking pulse rate every 30 minutes, and documenting the client's condition every 15 minutes do not address the immediate need for a formal restraint prescription within 4 hours to manage the client's acute mania effectively.

Correct Answer: A

Rationale: Corrected Rationale: Weak femoral pulses are an expected finding in an infant with coarctation of the aorta. The narrowing of the aorta leads to decreased blood flow to the lower extremities, resulting in weak or absent femoral pulses. Frequent nosebleeds (Choice B) are not typically associated with coarctation of the aorta. Upper extremity hypotension (Choice C) is not a common finding in coarctation of the aorta; instead, blood pressure is usually elevated in the upper extremities. Increased intracranial pressure (Choice D) is not directly related to coarctation of the aorta.

Correct Answer: A

Rationale: Corrected Rationale: Bradypnea, or slow breathing, is a common sign of opioid toxicity. When a client is experiencing opioid toxicity, the respiratory system is usually the most affected, leading to a decrease in the respiratory rate (bradypnea). Tachycardia (increased heart rate), hypertension (high blood pressure), and diaphoresis (excessive sweating) are not typical manifestations of opioid toxicity. Therefore, the correct answer is bradypnea.

Correct Answer: B

Rationale: The correct answer is B: 'Check your pulse before taking this medication.' When a patient is prescribed digoxin, it is crucial to monitor their pulse rate because digoxin can cause bradycardia (slow heart rate) as a side effect. In contrast, choices A, C, and D are incorrect. Taking digoxin with meals is not necessary; it should be taken consistently at the same time every day. Taking digoxin with an antacid is not recommended as it can interfere with the absorption of the medication. While digoxin can cause hypokalemia (low potassium levels), patients should not increase their potassium intake without healthcare provider guidance to avoid potential complications.

Correct Answer: C

Rationale: The correct action the nurse should take when caring for a client with a chest tube is to keep the drainage system below the level of the client's chest. This positioning helps prevent fluid from flowing back into the pleural space, ensuring proper drainage and effective functioning of the chest tube. Clamping the chest tube intermittently or stripping it frequently can lead to complications and should be avoided. Emptying the drainage collection chamber at specific intervals may vary based on institutional protocols, but it should be done when it is no more than two-thirds full to prevent backflow and maintain accurate monitoring of drainage output.
