Correct Answer: A

Rationale: The correct answer is A: 'I don't have muscle spasms as frequently.' Dantrolene is a medication that relaxes skeletal muscles and is commonly prescribed to treat muscle spasms in clients with multiple sclerosis. Therefore, a reduction in muscle spasms frequency would be an indication of the medication's effectiveness. Choices B, C, and D are incorrect because dantrolene is not indicated for preventing colds, improving nerve pain, or easing urination. The focus should be on the medication's intended purpose, which is to address muscle spasms in clients with multiple sclerosis.

Correct Answer: C

Rationale: The correct answer is C, 'Hypertension.' Prednisone, a corticosteroid, can lead to hypertension as an adverse effect. Prednisone can cause sodium retention and potassium loss, leading to increased blood pressure. Weight loss (choice A) is not a common adverse effect of prednisone; in fact, weight gain is more common. Hypoglycemia (choice B) is not typically associated with prednisone use; instead, hyperglycemia is a common concern. Hyperkalemia (choice D) is also unlikely with prednisone use; instead, hypokalemia is a potential electrolyte imbalance.

Correct Answer: B

Rationale: The correct answer is to monitor the client's skin under the halo vest. This is important to assess for signs of skin issues such as excessive sweating, redness, or blistering, which can lead to skin breakdown and infection. Choice A is incorrect because while inspecting the pin site is important, it should be done more frequently than every 4 hours. Choice C is incorrect as the halo device should be supported by the client's body weight, not personnel, when repositioning. Choice D is incorrect because applying powder frequently can increase the risk of skin irritation and infection.

Correct Answer: B

Rationale: The correct answer is B: Respiratory alkalosis. In this scenario, the client is experiencing respiratory alkalosis due to hyperventilation. Hyperventilation leads to excessive loss of carbon dioxide, causing a decrease in hydrogen ion concentration and an increase in pH levels. Choices A, C, and D are incorrect. Respiratory acidosis is characterized by high PaCO2 and low pH. Metabolic acidosis is associated with low HCO3- levels and low pH. Metabolic alkalosis is marked by high HCO3- levels and high pH. In this case, the ABG results indicate respiratory alkalosis.

Correct Answer: B

Rationale: The correct answer is B: 'Consume high-calorie foods.' Clients with COPD often have increased energy needs due to the work of breathing. Consuming high-calorie, high-protein foods can help provide the necessary energy and prevent weight loss. Choice A is incorrect because eating three large meals daily may lead to increased shortness of breath due to a full stomach putting pressure on the diaphragm. Choice C is incorrect because caffeinated drinks can contribute to dehydration, which is not ideal for clients with COPD. Choice D is incorrect because drinking fluids during mealtime can cause bloating and early satiety, making it difficult for clients to consume enough calories.
