Correct Answer is B

Explanation

A. Glasgow Coma Scale rating of 15: A Glasgow Coma Scale (GCS) rating of 15 is a positive sign indicating that the client is fully conscious and oriented. It is not an adverse effect of mannitol.
B. Crackles on auscultation: Crackles, also known as rales, can indicate fluid overload or pulmonary edema, which can be an adverse effect of mannitol. Mannitol can cause shifts of fluid, including into the lungs, leading to pulmonary edema.
C. Increase in urinary output: Mannitol is an osmotic diuretic, and an increase in urinary output is an expected and therapeutic effect of the medication. It is not considered an adverse effect.
D. Intracranial pressure reading of 12 mmHg: A decrease in intracranial pressure is a therapeutic effect of mannitol, and a reading of 12 mmHg is generally within a normal range. It is not considered an adverse effect.

A. Bradycardia B. Hypotension C. Polyuria D. Nausea

Correct Answer is B

Explanation

A. Bradycardia:
Bradycardia is not a typical manifestation of an allergic reaction. Allergic reactions are more likely to involve symptoms such as rash, itching, swelling, and cardiovascular symptoms like tachycardia rather than bradycardia.
B. Hypotension:
This is the correct answer. Hypotension (low blood pressure) can be a sign of an allergic reaction, particularly in severe cases. Anaphylaxis, a severe allergic reaction, can lead to a rapid drop in blood pressure.
C. Polyuria:
Polyuria, excessive urine production, is not a typical manifestation of an allergic reaction. Allergic reactions are more likely to involve skin, respiratory, and cardiovascular symptoms.
D. Nausea:
Nausea can be a side effect of medications, but it is not a specific manifestation of an allergic reaction. Allergic reactions are more likely to present with symptoms such as skin rash, itching, or respiratory distress.
