Question 1 of 5
The nurse initiates an infusion of piperacillin-tazobactam for a client with a urinary tract infection. Five minutes into the infusion, the client reports not feeling well. Which client manifestation should the nurse identify as a reason to stop the infusion?
Correct Answer: D
Rationale: A scratchy throat (
D) may indicate anaphylaxis, requiring immediate cessation of piperacillin-tazobactam (matches 55-Q2). Hypertension (
A), bradycardia (
B), and pupillary constriction (
C) are not typical allergic response signs.
Question 2 of 5
A client is receiving a secondary infusion of azithromycin 500 mg in 500 mL of normal saline (NS) to be infused over 2 hours. The intravenous (IV) administration set delivers 10 gtt/mL. How many gtt/min should the nurse regulate the infusion? (Enter Calculation(ans only)al value only. If rounding is required, round to the nearest whole number.)
Correct Answer: 42
Rationale: Infusion rate: 500 mL / 2 hr = 250 mL/hr. Drops per minute: (250 mL/hr × 10 gtt/mL) / 60 min = 41.67, rounded to 42 gtt/min (matches 55-Q54). This ensures accurate azithromycin delivery.
Question 3 of 5
A client taking atorvastatin develops an increased serum creatine phosphokinase (CK) level. The nurse should assess the client for the onset of which problem?
Correct Answer: B
Rationale: Elevated CK with atorvastatin indicates myopathy, causing muscle tenderness (
B) (matches 55-Q31). Edema (
A), nausea/vomiting (
C), and bruising (
D) are unrelated to CK.
Question 4 of 5
The nurse initiates an infusion of piperacillin-tazobactam for a client with a urinary tract infection. Five minutes into the infusion, the client reports not feeling well. Which client manifestation should the nurse identify as a reason to stop the infusion?
Correct Answer: D
Rationale: A scratchy throat (
D) may indicate anaphylaxis, requiring immediate cessation of piperacillin-tazobactam (matches 55-Q2). Hypertension (
A), bradycardia (
B), and pupillary constriction (
C) are not typical allergic response signs.
Question 5 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: C
Rationale: Tamsulosin, an alpha-blocker, can cause hypotension and dizziness (
C) (matches 55-Q29/32). Bladder scans (
A) and urine output (
B) assess BPH, not adverse effects. Daily weights (
D) monitor fluid status, not tamsulosin risks.
