RN HESI Pharmacology Exam 3 Questions
Extract:
Question 1 of 5
A client who is taking dextroamphetamine-amphetamine extended-release tablets for attention deficit hyperactivity disorder (ADHD), reports about having difficulty sleeping at night. Which assessment is most important for the nurse to obtain?
Correct Answer: C
Rationale: Dextroamphetamine-amphetamine, a stimulant, can cause insomnia if taken late. Determining dose timing identifies if adjusting to earlier administration reduces sleep issues. Bedtime routines, anxiety, or caffeine are secondary considerations.
Question 2 of 5
A glucagon emergency kit is prescribed for a client with type 1 diabetes mellitus. When should the nurse instruct the client and family that glucagon needs to be administered?
Correct Answer: C
Rationale: Glucagon raises blood glucose in severe hypoglycemia (e.g., unconsciousness), preventing complications. It’s not for hyperglycemia, sick days, or diabetic ketoacidosis, which require insulin and other treatments.
Question 3 of 5
The nurse is teaching a client how to use an inhaler device. Which client statement indicates to the nurse that the client understands the instructions?
Correct Answer: C
Rationale: Rinsing the mouth after inhaler use, especially with corticosteroids, prevents oral thrush by removing residual medication. Bedtime-only use, meal timing, or caffeine limits are incorrect and unrelated to proper inhaler technique.
Question 4 of 5
The nurse is assessing the eyes of a client who just received mydriatic eye drops. Which physiological function of the eye will not respond during the therapeutic period after administration of the eye drops?
Correct Answer: A
Rationale: Mydriatic drops dilate pupils, inhibiting constriction by blocking parasympathetic response. Refraction, convergence, and accommodation (though impaired) are less directly affected during the therapeutic period.
Question 5 of 5
The nurse is caring for an adult client who is taking digoxin. Which laboratory value should be reported to the healthcare provider immediately? Reference Range: Sodium [Adult 136 to 145 mEq/L (136 to 145 mmol/L)] Digoxin level [0.8 to 2.0 ng/mL (0.6 to 13 nmol/L)] Potassium (K+) [Adult: 3.5 to 5.0 mEq/L (3.5 to 5.0 mmol/L)] Creatinine [0.5 to 1.1 mg/dL (44 to 97 μmol/L)]
Correct Answer: C
Rationale: Hypokalemia (3.2 mEq/L) increases digoxin toxicity risk, potentially causing arrhythmias. Immediate reporting allows potassium correction. Mild hyponatremia, normal creatinine, and therapeutic digoxin levels are less urgent.
