Correct Answer: D

Rationale: In cases of digoxin toxicity, IV digoxin immune fab (Digibind) is the antidote and should be administered first to counteract the effects of digoxin poisoning. This intervention is crucial in managing digoxin overdose and should be initiated promptly to improve patient outcomes. Activated charcoal and gastric lavage are not effective in treating digoxin poisoning and may not be beneficial at this stage. While obtaining an electrocardiogram is important to assess cardiac function, administering the antidote should take precedence to address the immediate life-threatening effects of digoxin toxicity.

Correct Answer: C

Rationale: Hypertension is a serious complication of glomerulonephritis, as it can lead to further renal damage. A blood pressure reading of 150/95 mm Hg is elevated and should be reported promptly to the healthcare provider for immediate management to prevent complications. Dark-colored urine can be a common symptom of glomerulonephritis due to blood in the urine but is not as urgent as managing hypertension. Mild periorbital edema can also be seen in glomerulonephritis but is not as concerning as elevated blood pressure. Urine output of 250 mL in 24 hours indicates oliguria, which is a concern, but addressing hypertension takes priority to prevent further renal damage.

Correct Answer: D

Rationale: The correct answer is D. Wearing long sleeves and pants is an effective measure to prevent tick bites, which can transmit Lyme disease. Ticks are commonly found in wooded areas and tall grass, so covering exposed skin helps reduce the risk of tick bites and subsequently lowers the risk of contracting Lyme disease. Choices A, B, and C do not directly address the mode of transmission of Lyme disease. Option A pertains to respiratory protection against dust, Option B focuses on wound care, and Option C relates to water safety, none of which are directly related to preventing Lyme disease transmission.

Correct Answer: D

Rationale: Encouraging the child to use the bathroom before bed is a helpful recommendation to prevent nighttime bedwetting. Bedwetting can sometimes reoccur due to stress or other factors, and ensuring the child empties their bladder before sleeping may reduce the likelihood of bedwetting episodes. Choice A is incorrect because while bedwetting is common in children, it is essential to provide practical solutions rather than just reassurance. Choice B is not the best option for a child who has recently started bedwetting again after being dry, as it may not address the underlying cause. Choice C is inappropriate and harmful as punishing the child for bedwetting can lead to psychological distress and worsen the situation.

Correct Answer: C

Rationale: Monitoring for signs of infection at the surgical site is crucial after an appendectomy as it helps in early detection and treatment of any potential complications. This intervention is essential for ensuring the child's proper healing and recovery post-surgery. Encouraging early ambulation is generally beneficial post-operatively but may not be the priority immediately after an appendectomy. Applying warm compresses to the incision site may not be indicated as it can increase the risk of infection. Providing a high-fiber diet immediately post-op is not recommended as the digestive system needs time to recover from surgery.
