ATI RN Pharmacology Online Practice 2023 A Questions
Question 1 of 5
The client's calcium level is low. What will be the nurse's primary concern?
Correct Answer: A
Rationale: Low calcium (hypocalcemia) risks seizures-nerve excitability rises, per physiology-outweighing fractures (chronic), hypoglycemia (unrelated), or depression (indirect). Acute neurologic risk drives concern, per assessment.
Question 2 of 5
The nurse administers IV mannitol to a client with cerebral edema. Which parameter should the nurse monitor closely?
Correct Answer: A
Rationale: Mannitol, an osmotic diuretic, reduces cerebral edema by drawing fluid into the vasculature, excreted via urine. Monitoring urine output ensures efficacy and prevents fluid overload or renal strain, critical in brain injury. BP and pupils matter but follow diuresis. Temperature is unrelated. Urine output aligns with mannitol's action, key in cerebral edema where ICP reduction hinges on fluid shift, making A the priority parameter.
Question 3 of 5
The patient is scheduled to have an EEG to confirm the presence of a sleep disorder. The patient asks the nurse to describe NREM stage 3 sleep. What is the best response by the nurse?
Correct Answer: C
Rationale: NREM stage 3, deep sleep, restores energy-lack causes fatigue and mood dips, per sleep physiology. Stage 1 is lightest, anxiety-sensitive. Dreaming is REM, not here-irritability ties to REM loss. Paradoxical is REM. Deep sleep's role explains EEG focus, answering accurately.
Question 4 of 5
A patient is receiving intravenous (IV) potassium supplements. What is the most important nursing implication when administering this drug?
Correct Answer: B
Rationale: IV potassium must always be diluted in IV fluids and administered via an infusion pump to prevent rapid infusion, which can cause life-threatening cardiac arrhythmias. Administering undiluted potassium or too quickly can lead to hyperkalemia and cardiac arrest. While central lines (A) are sometimes used, potassium can also be given through a peripheral IV if properly diluted. Chilling potassium (C) is unnecessary and could cause discomfort. Preservatives (D) are not a primary concern with IV potassium administration.
Question 5 of 5
The client's calcium level is low. What will be the nurse's primary concern?
Correct Answer: A
Rationale: Low calcium (hypocalcemia) risks seizures-nerve excitability rises, per physiology-outweighing fractures (chronic), hypoglycemia (unrelated), or depression (indirect). Acute neurologic risk drives concern, per assessment.
