Correct Answer: B

Rationale: The twelfth cranial nerve is the hypoglossal nerve, which controls the muscles of the tongue. The other choices are incorrect because the trochlear nerve is the fourth cranial nerve responsible for eye movement, the olfactory nerve is the first cranial nerve responsible for the sense of smell, and there are only twelve cranial nerves, so there is no thirteenth cranial nerve.

Correct Answer: C

Rationale: Dermatitis can closely resemble and mimic dandruff due to similar symptoms like flaking and itching. Lice infestation (choice A) is characterized by the presence of lice and their eggs attached to the hair shaft, different from dandruff. Scabies (choice B) is a contagious skin condition caused by mites, presenting as burrows, rashes, and intense itching, not typically resembling dandruff. Acne vulgaris (choice D) is a skin condition involving hair follicles and sebaceous glands, manifesting as pimples and inflammation, which is distinct from dandruff.

Correct Answer: C

Rationale: The correct answer is C. Addressing the absence of three staff members should be the nurse manager's priority as it directly impacts staffing levels and patient care. This situation can lead to staffing shortages, affecting patient safety and workload distribution. Option A, lack of transport assistance, although important, can be addressed after ensuring adequate staffing. Option B involves a client's preference and can be addressed by assigning care appropriately. Option D, a disagreement between two nurses, is important but can be addressed after ensuring adequate staffing and patient care.

Correct Answer: D

Rationale: The correct answer is D: IV bolus, followed by continuous infusion. In the initial treatment of hyperglycemia in a client with diabetic ketoacidosis, insulin is administered via IV bolus to quickly reduce blood glucose levels, followed by a continuous infusion to maintain control. Subcutaneous and intramuscular routes are not used in this situation as they are not rapid or predictable enough to address the acute hyperglycemia seen in diabetic ketoacidosis. IV bolus alone without the continuous infusion may not provide sustained control of blood glucose levels, making choice C incorrect.

Correct Answer: D

Rationale: The post-icteric stage of viral hepatitis is accurately described as the stage where jaundice and dark urine occur due to the accumulation of bilirubin. The resolution of jaundice and normalization of urine color are seen in this stage. Choices A, B, and C are incorrect. In the prodromal stage, symptoms like fatigue and malaise appear before jaundice. The icteric stage is characterized by jaundice, not flu-like symptoms. The pre-icteric stage does not typically involve elevated urine bilirubin levels, as this occurs after the icteric stage.
