Correct Answer: B

Rationale: The correct answer is B: Administer calcium gluconate. Magnesium sulfate can cause respiratory depression, leading to a low respiratory rate. Calcium gluconate is the antidote for magnesium sulfate toxicity, as it antagonizes the effects of magnesium on the neuromuscular junction. Administering calcium gluconate helps reverse the respiratory depression caused by magnesium sulfate. Increasing IV fluids (Choice A) is not directly related to treating respiratory depression. Vigorously stimulating the patient (Choice C) can exacerbate respiratory depression. Instructing the patient to take deep breaths (Choice D) may not be effective in addressing the underlying cause of respiratory depression due to magnesium sulfate toxicity.

Correct Answer: B

Rationale: The correct answer is B: Jejunostomy tube. This tube is chosen because the patient has a history of aspiration pneumonia, which puts them at risk for aspiration if feeds are administered into the stomach. By administering feeds through a jejunostomy tube, the risk of aspiration pneumonia is minimized as the feed bypasses the stomach. Nasogastric tube (A) and Nasointestinal tube (C) would still deliver feeds to the stomach, increasing the risk of aspiration. PEG tube (D) is also not ideal as it delivers feeds directly to the stomach, which is not recommended for patients at risk for aspiration.

Correct Answer: A

Rationale: The correct answer is A because habit training involves keeping a bladder diary to identify patterns and develop a toileting schedule. This helps in promoting regular voiding habits. B is incorrect because timed voiding isn't solely based on the patient's urge to void, but rather on a predetermined schedule. C is incorrect as prompted voiding involves reminding patients to use the restroom at regular intervals, not just asking if they are wet or dry. D is incorrect because elevating feet in patients with edema may help reduce swelling but has no direct impact on nighttime voiding.

Correct Answer: B

Rationale: The correct answer is B: Addressing possible barriers to adherence. This is crucial because adherence to the antiretroviral drug regimen is key for successful therapy in HIV patients. By identifying and addressing barriers such as medication side effects, cost, or forgetfulness, nurses can help patients stay on track with their treatment. Other choices are incorrect: A: Promoting complementary therapies is not the priority in initiating antiretroviral therapy. Adherence to the prescribed regimen is more critical. C: Educating about the pathophysiology of HIV is important, but it may not directly impact the success of the therapy as much as addressing adherence barriers. D: While follow-up blood work is necessary, it is not as immediate and impactful as addressing adherence barriers at the beginning of therapy.

Correct Answer: A

Rationale: The correct answer is A because the postpartum patient who has had four saturated pads during the last 12 hours should receive further assessment. This indicates excessive postpartum bleeding (postpartum hemorrhage), which is a critical complication that requires immediate intervention to prevent complications like hypovolemic shock. Monitoring vital signs, assessing for signs of shock, evaluating uterine tone, and determining the cause of bleeding are crucial steps in managing postpartum hemorrhage. Choices B, C, and D are not the correct answers because: B: A patient with Class II heart disease complaining of frequent coughing is more likely experiencing cardiac-related issues and requires evaluation and management by a cardiologist. C: A patient with gestational diabetes and a fasting blood sugar level of 100 mg/dL is within the normal range and does not require immediate further assessment. D: A postcesarean patient with active herpes lesions on the labia requires appropriate management of the herpes infection but does not necess
