1. The camp nurse asks the children preparing to swim in the lake if they have applied sunscreen. The nurse reminds the children that chemical sunscreens are most effective when applied:
- A. Immediately before swimming
- B. 15 minutes before exposure to the sun
- C. Immediately before exposure to the sun
- D. At least 30 minutes before exposure to the sun
Correct answer: D
Rationale: Chemical sunscreens are most effective when applied at least 30 minutes before exposure to the sun to allow them to penetrate the skin and provide optimal protection. Applying sunscreen immediately before swimming (Choice A) or immediately before exposure to the sun (Choice C) may not provide sufficient time for the sunscreen to be absorbed and offer proper protection. Applying sunscreen 15 minutes before sun exposure (Choice B) is also not ideal as it may not allow enough time for the sunscreen to work effectively. Therefore, the correct answer is to apply chemical sunscreen at least 30 minutes before exposure to the sun to ensure it can be absorbed and offer the intended protection. It is important to reapply sunscreen after swimming or sweating to maintain its effectiveness.
2. A client is receiving morphine sulfate subcutaneously for pain. Because morphine sulfate has been prescribed for this client, which nursing action would be included in the plan of care?
- A. Encourage fluid intake.
- B. Monitor the client's temperature.
- C. Maintain the client in a supine position.
- D. Encourage the client to cough and deep breathe.
Correct answer: D
Rationale: Morphine sulfate suppresses the cough reflex, which can lead to the retention of secretions in the lungs. Encouraging the client to cough and deep breathe helps prevent pneumonia by clearing the airways of any accumulated secretions. This intervention is crucial in clients receiving morphine sulfate to maintain optimal respiratory function.
3. Isosorbide mononitrate (Imdur) is prescribed for a client with angina pectoris. The client tells the nurse that the medication is causing a chronic headache. The nurse appropriately suggests that the client:
- A. Cut the dose in half.
- B. Discontinue the medication.
- C. Take the medication with food.
- D. Contact the healthcare provider (HCP).
Correct answer: C
Rationale: Isosorbide mononitrate can cause headaches, which usually disappear during continued therapy. Taking the medication with food or meals can help alleviate the headache. It is important to recommend this approach before considering dose adjustments or discontinuation of the medication. Contacting the healthcare provider would be necessary if the headache persists despite taking the medication with food.
4. Bethanechol chloride (Urecholine) is prescribed for a client with urinary retention. Which disorder would be a contraindication to the administration of this medication?
- A. Gastric atony
- B. Urinary strictures
- C. Neurogenic atony
- D. Gastroesophageal reflux
Correct answer: B
Rationale: Bethanechol chloride (Urecholine) should not be administered to clients with urinary strictures as it can contract the bladder and increase pressure within the urinary tract. In individuals with urinary strictures, this elevated pressure may lead to bladder rupture. Therefore, caution is advised when considering the use of Bethanechol chloride in clients with urinary strictures to prevent potential complications. Gastric atony, neurogenic atony, and gastroesophageal reflux are not contraindications for the administration of Bethanechol chloride for urinary retention.
5. When a client taking warfarin sodium (Coumadin) is prescribed ciprofloxacin (Cipro), the nurse should closely monitor the client for which potential effect of this drug interaction?
- A. Increased risk of bleeding
- B. Decreased warfarin effectiveness
- C. Increased risk of thrombosis
- D. Decreased ciprofloxacin effectiveness
Correct answer: A
Rationale: When ciprofloxacin (Cipro) is given with warfarin sodium (Coumadin), it can potentiate the effects of warfarin, leading to an increased risk of bleeding. Therefore, the nurse should closely monitor the client's INR levels and watch for signs of bleeding such as bruising, petechiae, or black tarry stools.
