To prevent a Valsalva maneuver in a client recovering from an acute myocardial infarction, the nurse would:

Correct Answer: B

Rationale: Administering stool softeners daily is crucial to prevent straining during defecation, which can lead to the Valsalva maneuver. Straining can increase intrathoracic pressure, decrease venous return to the heart, and reduce cardiac output, potentially worsening the client's condition. If constipation occurs, the use of laxatives may be necessary to avoid straining. Administering antidysrhythmics on an as-needed basis is not indicated for preventing the Valsalva maneuver; they are used to manage dysrhythmias. Strict bed rest is not necessary and may lead to complications such as deconditioning, DVT, and respiratory issues in the absence of specific medical indications.

Correct Answer: D

Rationale: The correct answer is 'Wet to dry dressing.' Wet to dry dressing is a method of wound debridement that involves applying sterile soaked gauze to the wound, allowing it to dry and stick to the wound. When the dressing is removed, it pulls away drainage and debris, aiding in wound debridement. Choice A, 'Dry dressing,' does not actively assist in debridement as it does not collect or remove debris from the wound. Choice B, 'Transparent dressing,' is primarily used for maintaining a moist environment and wound observation, not for debridement. Choice C, 'Composite dressing,' combines multiple layers for different wound care purposes but is not specifically designed for debridement like wet to dry dressing.

Correct Answer: B

Rationale: The correct answer is B: Pegylated α-interferon (PEG-Intron, Pegasys) SQ weekly. Pegylated α-interferon is typically administered once weekly, not daily. Therefore, this medication requires further discussion with the healthcare provider before administration to ensure the correct dosing frequency. Ribavirin, choice A, is appropriate for chronic hepatitis C treatment. Choices C and D, Diphenhydramine and Dimenhydrinate, are commonly used for symptomatic relief in patients with hepatitis C and do not require further discussion with the healthcare provider in this context.

Correct Answer: C

Rationale: A Jackson-Pratt drain is a type of active wound drain that may be placed following a surgical procedure. This drain actively draws excess blood and fluid out of the wound. If clots develop within the tubing, the nurse should strip the tubing by milking it in a direction away from the client. This action helps to ensure the drain remains patent and effective. Option A is incorrect because the tubing should be milked away from the client, not towards. Option B is incorrect as the drain should be emptied based on the healthcare provider's orders, not at a fixed volume. Option D is incorrect because the level of the drain should be below the level of the incision to allow drainage by gravity.

Correct Answer: C

Rationale: The correct answer is: 'The medication will prevent irritation of the enlarged veins.' Esophageal varices are dilated submucosal veins. The therapeutic action of H2-receptor blockers in patients with esophageal varices is to prevent irritation and bleeding from the varices caused by reflux of acidic gastric contents. While ranitidine can decrease the risk of peptic ulcers, reduce nausea, and help prevent aspiration pneumonia, the primary purpose of H2-receptor blockade in this patient is to prevent irritation and bleeding from the varices, not the other listed effects.

Correct Answer: A

Rationale: In acute severe pancreatitis, there is a risk of respiratory failure as a complication, making the maintenance of normal respiratory function the priority outcome. This patient may develop respiratory issues due to the inflammatory process affecting the diaphragm. While pain control, absence of ongoing pancreatic disease, and fluid/electrolyte balance are crucial, they are secondary to ensuring adequate oxygenation and ventilation to prevent respiratory compromise.

Correct Answer: C

Rationale: The correct answer is the patient's temperature of 100.8°F (38.2°C). In a patient who received a liver transplant 1 week ago, a fever is a significant finding that should be promptly communicated to the health care provider. Post-transplant patients are at high risk of infections, and fever can often be the initial indicator of an underlying infectious process. The other findings listed in choices A, B, and D are important and should be addressed, but they do not take precedence over a potential infection post-liver transplant. Dry palpebral and oral mucosa may indicate dehydration, crackles at bilateral lung bases may suggest fluid overload or infection, and no bowel movement for 4 days could indicate a bowel obstruction or ileus. However, in the context of a recent liver transplant, an elevated temperature is the most concerning and requires immediate attention to rule out infection.

Correct Answer: B

Rationale: To evaluate treatment effectiveness for a patient with hepatic encephalopathy, requesting the patient to walk with eyes closed is crucial. This test assesses the patient's balance, gait, and coordination, which can be impaired in hepatic encephalopathy due to altered mental status and brain function. Walking with eyes closed challenges the patient's sensory input and proprioception, providing valuable information on improvement or deterioration in neurological function. Asking the patient to extend both arms forward is used to check for asterixis, a sign often seen in hepatic encephalopathy, but it is not specific for evaluating treatment effectiveness. Performing the Valsalva maneuver is unrelated to assessing hepatic encephalopathy and is more commonly used in cardiac evaluations. Observing the patient's breathing pattern may be important in other conditions but is not directly relevant to evaluating treatment effectiveness for hepatic encephalopathy.

Correct Answer: C

Rationale: In the post-anesthesia care unit, clients may experience shivering or chills due to a drop in body temperature after surgery. Meperidine (Demerol) can be prescribed to alleviate shivering in cold clients. The prone position (lying face down) and deep breathing exercises are not interventions specifically indicated for addressing shivering due to low body temperature. Therefore, administering meperidine as ordered is the most appropriate action to manage the client's shivering in this scenario.
