Correct Answer: C

Rationale: The correct answer is C. In hypothyroidism, the thyroid gland is underactive, leading to symptoms like puffiness of the face and hands due to fluid retention. This occurs as a result of decreased metabolism. Options A and B are symptoms of hyperthyroidism, where the thyroid gland is overactive. Option D is a symptom of goiter, which is thyroid gland swelling, not specific to hypothyroidism. Therefore, the correct answer is C based on the characteristic symptoms of hypothyroidism.

Correct Answer: C

Rationale: The correct answer is C: Increased risk of respiratory complications. Clients with myasthenia gravis, Guillain-Barre Syndrome, or amyotrophic lateral sclerosis all experience muscle weakness, including respiratory muscles, leading to a higher risk of respiratory complications such as difficulty breathing or respiratory failure. This is due to the involvement of the neuromuscular system in these conditions. Choices A, B, and D are incorrect because they do not directly correlate with the respiratory complications commonly seen in these specific neuromuscular disorders.

Correct Answer: B

Rationale: The correct answer is B: Fluorouracil (5-fluorouracil, 5-FU). Fluorouracil is a commonly used chemotherapy drug for treating advanced liver cancer. It works by inhibiting the growth of cancer cells. This drug is specifically effective in targeting rapidly dividing cells, which is a characteristic of cancer cells. Fluorouracil is often used in combination with other chemotherapy drugs to improve treatment outcomes. Summary of other choices: A: Fluoxymesterone (Halotestin) - This is an androgen hormone used to treat certain types of breast cancer, not liver cancer. C: Tamoxifen (Nolvadex) - This is a hormonal therapy drug used in breast cancer, not liver cancer. D: Megestrol (Megace) - This is a hormonal therapy drug used for certain types of cancers, but not typically for liver cancer.

Correct Answer: C

Rationale: The correct answer is C: Muscle weakness. Metolazone is a diuretic that can lead to low potassium levels, causing muscle weakness. Instructing the patient to report muscle weakness is crucial to prevent any potential serious complications. Numb hands, gastrointestinal distress, and nightmares are not commonly associated with metolazone and do not pose as immediate risks as muscle weakness does. It is essential to prioritize the most critical side effect to ensure the patient's safety and well-being.

Correct Answer: B

Rationale: The correct answer is B. A semiprivate room with one or two consistent caregivers is the most therapeutic setting for an agitated head-injured patient. Here's the rationale: 1. Consistency: Having one or two consistent caregivers provides the patient with a stable and familiar environment, which can help reduce agitation. 2. Privacy: A semiprivate room offers more privacy compared to a day room or a ward, which can help minimize external stimuli and promote relaxation. 3. Individualized care: In a semiprivate room, caregivers can focus more on the specific needs of the patient, leading to better management of agitation. 4. Reduced distractions: Being in a semiprivate room minimizes distractions and noise, which can be overwhelming for an agitated head-injured patient. Summary: A, C, and D are incorrect because they do not offer the same level of consistency, privacy, individualized care, and reduced distractions as a semiprivate room with one
