Correct Answer: A

Rationale: The correct answer is A, Propofol. Propofol is a short-acting anesthetic medication commonly used to induce moderate sedation for procedures like a colonoscopy. This medication provides rapid onset and recovery, making it an ideal choice for such procedures. Choice B, Pancuronium, is a neuromuscular blocking agent used for muscle relaxation during surgery and would not be appropriate for sedation during a colonoscopy. Choice C, Promethazine, is an antihistamine used for nausea and motion sickness, not for anesthesia. Choice D, Pentoxifylline, is a medication used to improve blood flow in patients with circulation problems and is not indicated for anesthesia during a colonoscopy.

Correct Answer: B

Rationale: The correct answer is B: 'Consume high-calorie, high-protein foods.' Clients with COPD often have increased energy needs due to the work of breathing. Consuming high-calorie, high-protein foods can help provide the necessary energy and prevent weight loss. Choice A is incorrect because eating three large meals daily may lead to increased shortness of breath due to a full stomach. Choice C is incorrect because limiting caffeinated drinks is important, but the recommendation should focus on reducing intake, not specifying a number. Choice D is incorrect because drinking fluids during mealtime can lead to early satiety, making it difficult for the client to consume enough calories.

Correct Answer: B

Rationale: Following a liver biopsy, the nurse should instruct the client to lie on the right side to promote hemostasis. This position helps apply pressure to the biopsy site, reducing the risk of bleeding. Instructing the client to lie on the left side (Choice A) would not provide the same benefit. Increasing fluid intake (Choice C) is generally beneficial post-procedure to prevent dehydration and promote healing. Decreasing fluid intake (Choice D) is not advisable as it can lead to dehydration and potential complications.

Correct Answer: C

Rationale: The client presents with bradycardia, diaphoresis, and chest pain, indicating reduced cardiac output. Atropine is the appropriate choice as it increases heart rate by blocking the parasympathetic nervous system. Lidocaine is used for ventricular arrhythmias, Adenosine for supraventricular tachycardia, and Verapamil for controlling heart rate in atrial fibrillation or atrial flutter. These medications are not suitable for the client's current presentation.

Correct Answer: C

Rationale: A low sodium diet is recommended for a client who has hypertension. Therefore, the nurse should recommend 3 oz of chicken breast as the best choice for the client's diet because it contains 30 - 90 mg of sodium. Choice A, 1 packet of reconstituted dry onion soup, and Choice B, 3 oz of lean cured ham, are high in sodium content, which is not suitable for a client with hypertension. Choice D, 1/2 cup of canned baked beans, is also high in sodium, making it a less suitable choice compared to 3 oz of chicken breast.
