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 meperidine (Demerol) for pain management. Which assessment finding requires immediate action?
- A. Constipation
- B. Drowsiness
- C. Respiratory rate of 10 breaths per minute
- D. Nausea
Correct answer: C
Rationale: A respiratory rate of 10 breaths per minute indicates respiratory depression, a severe side effect of meperidine (Demerol) that necessitates immediate intervention to prevent further complications. Constipation, drowsiness, and nausea are common but less urgent side effects that do not pose an immediate life-threatening risk. Respiratory depression can lead to respiratory arrest and must be addressed promptly to ensure the client's safety and well-being.
3. When reviewing laboratory results for a client receiving tacrolimus (Prograf), which laboratory result would indicate to the nurse that the client is experiencing an adverse effect of the medication?
- A. Blood glucose of 200 mg/dL
- B. Potassium level of 3.8 mEq/L
- C. Platelet count of 300,000 cells/mm³
- D. White blood cell count of 6000 cells/mm³
Correct answer: A
Rationale: An elevated blood glucose level of 200 mg/dL indicates an adverse effect of tacrolimus. This finding suggests hyperglycemia, which is a known adverse effect of the medication. Other potential adverse effects of tacrolimus include neurotoxicity and hypertension. Monitoring blood glucose levels is crucial to detect and manage this adverse effect promptly. Choices B, C, and D are not directly associated with adverse effects of tacrolimus. Potassium, platelet count, and white blood cell count are important parameters to monitor for other reasons but not specifically for detecting adverse effects of tacrolimus.
4. The client with ovarian cancer is being treated with vincristine (Oncovin). The nurse monitors the client, knowing that which of the following indicates a side effect specific to this medication?
- A. Diarrhea
- B. Hair loss
- C. Chest pain
- D. Numbness and tingling in the fingers and toes
Correct answer: D
Rationale: The correct answer is D: Numbness and tingling in the fingers and toes. Vincristine is known to cause peripheral neuropathy as a side effect, resulting in numbness and tingling in the fingers and toes. Diarrhea, hair loss, and chest pain are not typically associated with vincristine use.
5. When a client is taking lansoprazole (Prevacid), which question should the nurse ask during data collection to determine medication effectiveness?
- A. Has your appetite increased?
- B. Are you experiencing any heartburn?
- C. Do you have any problems with vision?
- D. Do you experience any leg pain when walking?
Correct answer: B
Rationale: When a client is taking lansoprazole (Prevacid), a gastric acid pump inhibitor used to treat gastroesophageal reflux disease (GERD), the nurse should ask if the client is experiencing any heartburn to determine medication effectiveness. Heartburn is a common symptom of GERD, and the reduction of heartburn indicates the effectiveness of lansoprazole in managing acid reflux symptoms. Choices A, C, and D are not relevant to assessing the effectiveness of lansoprazole for GERD.
