A client with a head injury is admitted to the hospital. Which finding indicates a need for immediate intervention?

Correct Answer: C

Rationale: In a client with a head injury, being drowsy but still arousable can be a sign of increased intracranial pressure, which necessitates immediate intervention. This presentation may indicate a deterioration in neurological status, requiring prompt assessment and management to prevent further complications. Choices A, B, and D are not indicative of an immediate need for intervention in this scenario. A Glasgow Coma Scale (GCS) score of 15 indicates the highest level of consciousness; pupils being equal and reactive to light suggest intact cranial nerve function, and memory loss about the injury event is common in head injuries and does not necessarily warrant immediate intervention.

Correct Answer: B

Rationale: The correct answer is B: Furosemide (Lasix). Furosemide is a diuretic that promotes fluid loss, and giving it before hemodialysis can lead to excessive fluid loss during the treatment, potentially causing hypovolemia. Withholding furosemide until after the dialysis session helps in preventing this complication. Choices A, C, and D are incorrect because calcium carbonate, spironolactone, and multivitamins are not typically contraindicated before hemodialysis in clients with chronic renal failure.

Correct Answer: A

Rationale: Muscle weakness and cramps are characteristic signs of hypokalemia, a condition marked by low levels of potassium in the blood. Potassium is essential for proper muscle function, and its deficiency can lead to muscle weakness and cramps. In the context of a client with a nasogastric tube to low intermittent suction, the loss of potassium through suctioning can contribute to the development of hypokalemia. Nausea and vomiting (choice B) are more commonly associated with gastrointestinal issues rather than hypokalemia. Constipation (choice C) is not a typical finding of hypokalemia; instead, it can be a sign of other gastrointestinal problems. Increased blood pressure (choice D) is not a direct manifestation of hypokalemia; in fact, low potassium levels are more commonly associated with decreased blood pressure.

Correct Answer: D

Rationale: In diabetes insipidus, the body loses excessive amounts of water, leading to diluted urine with low specific gravity. Therefore, when the urine specific gravity is within the normal range, it indicates that the kidneys are properly concentrating urine, which is a sign of effective treatment for diabetes insipidus. Choices A, B, and C are incorrect because in diabetes insipidus, there is polyuria (excessive urination), persistent thirst due to fluid loss, and potential weight loss due to fluid imbalance, so these findings would not indicate effective treatment.

Correct Answer: A

Rationale: The most effective strategy to reduce the incidence of type 2 diabetes in the community is hosting cooking classes on preparing healthy meals. This intervention provides practical skills and education that can directly impact dietary habits, leading to a decreased risk of developing type 2 diabetes. Offering free blood glucose screenings (Choice B) may help in early detection but does not address prevention. Distributing pamphlets on diabetes prevention (Choice C) provides information but lacks the interactive and hands-on approach of cooking classes. Organizing a community walking program (Choice D) promotes physical activity, which is beneficial, but dietary changes have a more significant impact on preventing type 2 diabetes.
