Correct Answer: D

Rationale: The correct answer is 'D: Blood pressure.' It is crucial to check the client's blood pressure before ambulating them, especially if they have a history of syncope. Monitoring blood pressure helps to prevent falls by ensuring that the client's blood pressure is stable enough to tolerate the activity. Choices A, B, and C are not as critical in this scenario. Checking pedal pulses, breath sounds, or oxygen saturation is important but not as crucial as assessing blood pressure when preparing to ambulate a client with a history of syncope.

Correct Answer: A

Rationale: The correct answer is A: Hypokalemia. In diabetes insipidus, there is excessive urination leading to fluid loss, which can result in electrolyte imbalances such as hypokalemia. Monitoring potassium levels is crucial to prevent complications like cardiac arrhythmias. Choices B, C, and D are incorrect. Ketonuria is typically seen in diabetic ketoacidosis, peripheral edema is more commonly associated with conditions like heart failure or kidney disease, and elevated blood pressure is not a direct complication of diabetes insipidus related to a pituitary gland tumor.

Correct Answer: B

Rationale: The correct answer is B: Altered mental status and tachypnea. These symptoms are indicative of PCP and severe HIV progression. Weight loss exceeding 10 percent of baseline body weight (choice A) may be seen in HIV/AIDS but is not specific to PCP. Creamy white patches in the oral cavity (choice C) are characteristic of oral thrush, which is more commonly associated with Candida infections in HIV patients. Normal ABGs with wet lung sounds in all lung fields (choice D) would not be expected with PCP, as it typically presents with hypoxemia and diffuse bilateral infiltrates on chest imaging.

Correct Answer: D

Rationale: Dry roasted almonds are the most suitable snack option for a client with chronic alcoholism and a decreased serum magnesium level because they are high in magnesium. Magnesium is essential in addressing the deficiency. Cheddar cheese and crackers (Choice A) do not contain as much magnesium as almonds. Carrot and celery sticks (Choice B) are healthy choices but do not provide a significant amount of magnesium. Beef bologna sausage slices (Choice C) are not a good choice as processed meats are not rich in magnesium.

Correct Answer: A

Rationale: The correct signs and symptoms indicative of hyperosmolar hyperglycemic nonketotic syndrome (HHNS) include increased heart rate, visual disturbances, and decreased mentation. These symptoms are often associated with HHNS due to the high blood glucose levels. Uremic frost, a sign of advanced kidney disease, is not typically associated with HHNS. Therefore, choices B and D are incorrect. However, choice C, 'Presence of uremic frost,' is incorrect as it is not typically associated with HHNS.
