Correct Answer: A

Rationale: The correct answer is A: Blood urea nitrogen (BUN). In CKD, the kidneys are unable to effectively filter waste products, leading to an increase in BUN levels. Elevated BUN indicates impaired kidney function. Calcium, potassium, and sodium levels may also be affected in CKD, but they are more likely to be imbalanced rather than consistently elevated. Calcium levels may be low due to impaired vitamin D activation, potassium levels may be high due to decreased excretion, and sodium levels can fluctuate based on fluid status. Therefore, while these lab values may be abnormal in CKD, BUN is the most consistently elevated marker of kidney dysfunction.

Correct Answer: A

Rationale: The correct answer is A: Administer oxygen. Oxygenation is the priority in stroke management to ensure adequate oxygen supply to the brain. Oxygen therapy can help reduce hypoxia, which is crucial in the acute phase of a stroke. Administering aspirin (B) is important but comes after ensuring oxygenation. Administering thrombolytics (C) requires proper assessment and diagnostic confirmation, not an immediate priority. Placing the client in a supine position (D) may worsen stroke symptoms if there is compromised blood flow, so it is not recommended as the initial action.

Correct Answer: B

Rationale: The correct answer is B: Clanging. Clanging refers to the phenomenon where words are chosen based on sound rather than meaning. In this case, the patient's speech demonstrates a pattern of words that rhyme or have similar sounds, despite lacking coherence or logical connection. This behavior is commonly seen in individuals with conditions like schizophrenia. Incorrect choices: A: Blocking - Blocking refers to sudden interruption or cessation of speech. This does not apply to the scenario described. C: Echolalia - Echolalia involves repetition of words or phrases spoken by others, not self-generated word patterns like in the scenario. D: Neologism - Neologism refers to the creation of new words or phrases with unique meanings, which is not reflected in the patient's speech pattern.

Correct Answer: A

Rationale: The correct answer is A: Perform a CT scan. This is the priority action because it helps determine if the stroke is ischemic or hemorrhagic, guiding treatment decisions. Monitoring blood pressure (B) is important but not the priority. Administering aspirin (C) can be considered after confirming the type of stroke. Administering thrombolytics (D) is indicated for ischemic stroke but should only be done after ruling out hemorrhagic stroke with a CT scan.

Correct Answer: D

Rationale: The correct answer is D: Scurvy. Scurvy is caused by a deficiency in vitamin C, which is essential for collagen synthesis. Without enough vitamin C, collagen production is impaired, leading to symptoms like bleeding gums, fatigue, and joint pain. Incorrect Choices: A: Rickets is caused by a deficiency in vitamin D, not vitamin C. B: Marasmus is a severe form of malnutrition due to inadequate intake of calories and protein, not specifically vitamin C. C: Kwashiorkor is a form of severe acute malnutrition typically caused by inadequate protein intake, not vitamin C deficiency. In summary, the correct answer is D (Scurvy) because it directly relates to inadequate intake of vitamin C, while the other choices are associated with different nutrient deficiencies.
