Correct Answer : D,E

(A) Serum Glucose Levels: Mannitol does not significantly affect glucose metabolism.

(B) Heart Rate: It does not directly impact heart rate, though secondary effects like dehydration may influence it.

(C) Respiration Rate: Mannitol does not directly impact respiratory function.

(D) Urine Output: Mannitol is an osmotic diuretic that increases urine output. Monitoring urine output helps assess the drug’s effectiveness and prevent dehydration or hypovolemia.

(E) Serum Potassium Levels: Mannitol causes diuresis, which can lead to electrolyte imbalances, including hypokalemia. Monitoring potassium levels helps prevent complications like arrhythmias.

Correct Answer is D

Explanation

(A) Restrict the patient’s fluid intake: Fluid restrictions are important but not the priority during administration. Monitoring for adverse effects like ototoxicity is more critical.

(B) Ensure the patient voids before administration: Furosemide is a diuretic, but voiding before administration is not required.

(C) Administer the dose rapidly to achieve quick results: Rapid IV push can cause ototoxicity and hypotension. It should be given slowly over 1-2 minutes.

(D) Monitor the patient for tinnitus: High-dose or rapid IV administration of furosemide can cause ototoxicity, leading to tinnitus and hearing loss.

A. Ask the HCP for Hypertonic Fluid Orders B. Ask the HCP for Isotonic Fluid orders C. Ask the HCP for a Colloid Infusion order D. Ask the HCP for Hypotonic Fluid orders

Correct Answer is D

Explanation

(A) Hypertonic Fluids: Would worsen hypernatremia by increasing sodium levels.

(B) Isotonic Fluids: These help with volume depletion but do not effectively reduce sodium levels.

(C) Colloid Infusions: Used for hypovolemia but do not correct sodium imbalances.

(D) Hypotonic Fluids: A sodium level of 155 mEq/L (hypernatremia) indicates dehydration, and hypotonic fluids (e.g., 0.45% NaCl) help shift water into cells and lower sodium levels.
