Question 1 of 5
The nurse is reviewing the client's laboratory values. Which serum laboratory value indicates to the nurse that a prescription for atorvastatin is having the desired effect for a client at risk for coronary artery disease?
Correct Answer: B
Rationale: Atorvastatin lowers LDL cholesterol, reducing coronary artery disease risk. Decreased LDL levels indicate effectiveness. HDL, CK, and PT are not primary measures of atorvastatin’s therapeutic effect.
Question 2 of 5
The client is a 75-year-old female admitted to the preoperative area to prepare for pacemaker insertion. Client reports she is having this done because her heart rate has been staying very low, she is always tired, and she has passed out once from low heart rate. Client has history of worsening symptomatic bradycardia. History of atrial fibrillation controlled. The nurse is preparing the client's plan of care. Select 4 findings that would indicate to the nurse that the administration of the vancomycin antibiotic would be safe to administer.
Correct Answer: A,B,D,F
Rationale: No known allergies reduce allergic reaction risks. A large vein IV minimizes thrombophlebitis. Prophylactic use is appropriate for surgery. Safe dosage prevents toxicity. Potassium and BUN, while important, are less specific to vancomycin safety.
Question 3 of 5
A client with allergic rhinitis is taking the over-the-counter antihistamine diphenhydramine HCL. Which instruction is most important for the nurse to provide this client?
Correct Answer: C
Rationale: Diphenhydramine causes significant drowsiness, posing a safety risk for driving. Avoiding driving is critical to prevent accidents. Dosing frequency (every 4-6 hours, not 8), gastric upset (minimal), and dry mouth are less urgent concerns.
Question 4 of 5
A client with benign prostatic hyperplasia receives a new prescription of tamsulosin. Which intervention should the nurse perform to monitor for an adverse reaction?
Correct Answer: D
Rationale: Tamsulosin, an alpha-1 blocker, can cause orthostatic hypotension, risking dizziness or fainting. Monitoring blood pressure detects this adverse reaction. Bladder scans, weights, or urine output assess BPH symptoms, not tamsulosin’s side effects.
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. Therapeutic digoxin, normal creatinine, and mild hyponatremia are less urgent.
