The nurse is completing the admission assessment of an adolescent client who is underweight and admitted to a psychiatric unit with a diagnosis of depression. Which finding requires notification to the healthcare provider?
Reference Range:
Potassium (K+) [3.5 to 5.0 mEq/L or 3.5 to 5.0 mmol/L]
White Blood Cell (WBC) [5000 to 10,000/mm3 or 5 to 10 x 109/L]
Body mass index of 21.
Blood pressure of 110/70 mm Hg.
Potassium level of 2.9 mEq/dl (2.9 mmol/L).
WBC of 10,000/mm3 (10 x 109/L).
The Correct Answer is C
Choice A rationale: A body mass index (BMI) of 21 is within the normal range and does not require immediate notification to the healthcare provider.
Choice B rationale: A blood pressure of 110/70 mm Hg is within the normal range for an adolescent and does not require immediate notification.
Choice C rationale: A potassium level of 2.9 mEq/dL (2.9 mmol/L) is below the normal range (hypokalemia) and requires notification to the healthcare provider due to the potential for adverse effects on cardiac and neuromuscular function.
Choice D rationale: A WBC of 10,000/mm3 (10 x 109/L) falls within the normal range and does not require immediate notification.

Correct Answer is B
Explanation
Choice A rationale: Hydrochlorothiazide is a diuretic and may contribute to electrolyte imbalances, but it is not the most concerning medication in this situation. Choice B rationale: Phenelzine is a monoamine oxidase inhibitor (MAOI), and the combination of an MAOI with certain foods or medications containing tyramine can lead
to a hypertensive crisis. The client's elevated blood pressure is of concern, and the nurse should notify the healthcare provider.
Choice C rationale: Losartan is an angiotensin II receptor blocker (ARB) used to treat hypertension. While it may contribute to blood pressure control, it is not the most concerning medication in this scenario.
Choice D rationale: Aspirin, at a dose of 81 milligrams, is often used for cardiovascular prophylaxis and is not the most concerning medication in this situation.
Correct Answer is B
Explanation
Choice A rationale: Asking the client about recent substance use is essential in assessing potential intoxication or withdrawal, which could contribute to the client's confused state. However, performing a mental status exam is the most important action to take.
Choice B rationale: The most important action for the nurse to take is to perform a mental status exam. This will help the nurse to assess the client's level of consciousness, orientation, memory, attention, mood, affect, thought process, and judgment. The mental status exam will also help the nurse to identify any signs of psychosis, delirium, dementia, or other mental disorders that may explain the client's behavior. Choice C rationale: Assessing the client from head-to-toe is a general nursing action but does not address the immediate need related to potential substance use. Choice D rationale: Determining the number of previous hospitalizations is relevant but does not address the current concern of substance use contributing to confusion.
