Correct Answer: C

Rationale: The correct answer is C: severe dehydration. In HHNK coma, the body tries to eliminate excess glucose through frequent urination, leading to dehydration. This results in decreased blood volume, causing hypotension and tachycardia. Signs include dry mucous membranes, poor skin turgor, and concentrated urine output. Fruity odor of the breath (A) is associated with diabetic ketoacidosis, not HHNK coma. Shallow, deep respirations (B) and profuse sweating (D) are not typically associated with HHNK coma.

Correct Answer: A

Rationale: The correct answer is A: Nystagmus. A phenytoin blood level of 35 mcg/ml is above the therapeutic range (usually 10-20 mcg/ml). Excessive levels can lead to symptoms such as nystagmus, which is an involuntary eye movement commonly seen with phenytoin toxicity. Nystagmus is a known side effect of phenytoin overdose. Choices B and C are incorrect because a level of 35 mcg/ml is not within the normal therapeutic range, so symptoms would be expected. Choice D, Slurred speech, is not typically associated with phenytoin toxicity.

Correct Answer: C

Rationale: The correct answer is C: The patient is apprehensive about discharge. This is the correct answer because the patient's fear of going home and being alone indicates apprehension about discharge, which is a common feeling among patients transitioning from the hospital to home care. This subjective data suggests that the patient may need additional support and education prior to discharge to address their fears and concerns. A: The patient can now perform the dressing changes without help - This is incorrect because the patient's fear of going home and being alone does not necessarily indicate their ability to perform dressing changes independently. B: The patient can begin retaking all of the previous medications - This is incorrect as the fear expressed by the patient is related to being alone at home, not to medication management. D: The patient’s surgery was not successful - This is incorrect as there is no indication in the subjective data provided that the surgery was not successful.

Correct Answer: A

Rationale: The correct answer is A: Neutrophil. Neutrophils are the most numerous type of WBC, typically comprising 50-70% of total WBC count. They are key players in the body's immune response, phagocytizing pathogens. Basophils, eosinophils, and lymphocytes are less numerous than neutrophils. Basophils are involved in allergic reactions, eosinophils combat parasitic infections, and lymphocytes play a critical role in adaptive immunity. However, in terms of sheer numbers, neutrophils outnumber the other types of WBC.

Correct Answer: D
