Correct Answer: C

Rationale: Continuously monitoring blood pressure is crucial in this case because nitroglycerin can cause hypotension as a side effect. Monitoring blood pressure allows the nurse to assess the client's response to the medication and detect any signs of hypotension promptly. This intervention is essential to ensure the effectiveness of nitroglycerin therapy and prevent potential complications. Administering the infusion via an infusion pump is important for accurate dosing but not the most critical at this moment. Obtaining the current serum potassium level is important but not the most immediate concern when the client is experiencing active chest pain. Teaching guided imagery may be beneficial for pain management, but in this scenario, monitoring blood pressure takes precedence due to the potential side effects of nitroglycerin.

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.

Correct Answer: A

Rationale: The correct action for the nurse to implement first is to remove the heating pad. Heating pads should not be used for suspected appendicitis as they can mask symptoms and potentially worsen inflammation. Choice B is not the priority as the position of comfort chosen by the UAP may be appropriate. Monitoring for signs of inflammation (Choice C) is important but not the initial action to address the immediate issue of the heating pad. Assessing the client's pain level (Choice D) can be done after removing the heating pad to evaluate the effectiveness of pain relief measures.

Correct Answer: A

Rationale: For orchitis, the recommended intervention is bedrest with scrotal support. This helps reduce swelling and discomfort in the scrotum. Antibiotics are generally not required for viral orchitis, so administering antibiotics for 10 days (Choice B) is not indicated. Applying heat (Choice C) may worsen swelling and should be avoided. Using an ice pack (Choice D) is not the preferred method for managing orchitis; it may not be as effective as providing support and rest for the scrotum.

Correct Answer: A

Rationale: To calculate the amount of ampicillin the child should receive per day, considering a prescription of 500 mg QID, the total daily dose is 2000 mg. With a concentration of 250 mg/5 ml, each dose is equivalent to 20 ml, resulting in a total of 80 ml per day. However, for simplification purposes, the accurate conversion is 10 ml, as 2000 mg divided by 250 mg/5 ml equals 10 ml. Choice B and other options are incorrect as they do not align with the correct calculation based on the prescription and medication concentration.
