Question 1 of 5
To control asthma, a client in a residential treatment facility uses a fluticasone propionate and salmeterol discus inhalation system, which provides an inhaled powdered form of these combined medications. Which instruction should the nurse provide to this client's caregivers?
Correct Answer: B
Rationale: Fluticasone/salmeterol is a maintenance therapy, not for acute asthma attacks, and should be used no more than twice daily to avoid side effects like oral thrush. Exhaling into the discus risks clumping the powder, and hypotension is not a common side effect.
Question 2 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 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
The nurse administers naloxone to a client with opioid-induced respiratory depression. One hour later, nursing assessment reveals that the client has a respiratory rate of 4 breaths/minute, oxygen saturation of 75%, and is unable to be aroused. Which action should the nurse implement?
Correct Answer: D
Rationale: Persistent respiratory depression (4 breaths/minute, 75% oxygen saturation) suggests ongoing opioid toxicity. A second dose of naloxone is needed to reverse opioid effects, as the initial dose may have worn off or been insufficient. GCS, chest tubes, or CPR do not address the opioid-related cause.
Question 5 of 5
A client who received a renal transplant three months ago is readmitted to the acute care unit with signs of graft rejection. While taking the client's history, the nurse determines that the client has been self-administering St. John's Wort, an herbal preparation, on the advice of a friend. Which information is most significant about this finding?
Correct Answer: C
Rationale: St. John's Wort induces liver enzymes (CYP3A4), reducing cyclosporine levels, an immunosuppressant critical for preventing transplant rejection. This interaction increases rejection risk, making it the most significant finding. Corticosteroid needs, sodium intake, or depression are less critical.
