Question 1 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 2 of 5
A male client is admitted for observation because he is reporting progressively increasing fatigue over the past month and a brief episode of dizziness that occurred today. He has a history of heartburn and indigestion that he self-treats with ibuprofen and antacids. Which assessment finding should the nurse report immediately to the healthcare provider? Reference Ranges: Hemoglobin [14 to 18 g/dL (8.7 to 11.2 mmol/L)] Hematocrit [42% to 52% (0.42 to 0.52 volume fraction)] Gastric pH [1.5 to 3.5]
Correct Answer: C
Rationale: A positive guaiac test indicates occult blood, suggesting gastrointestinal bleeding, potentially from ibuprofen use, which exacerbates gastric irritation. This requires immediate reporting for evaluation, given the client’s fatigue and dizziness. Normal hematocrit, slightly low hemoglobin, and normal gastric pH are less urgent.
Question 3 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: A
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 4 of 5
A female client with a history of peptic ulcer disease receives a prescription for misoprostol. Which information provided by the client indicates to the nurse a need for further teaching?
Correct Answer: A
Rationale: Misoprostol’s administration is not tied to menstrual cycles; it’s used to prevent NSAID-induced ulcers and requires no specific cycle timing. Contacting providers for conception risks, using contraception, and confirming negative pregnancy tests are critical due to teratogenic risks.
Question 5 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.
