A nurse is reinforcing teaching with a client who has a prescription for sildenafil to treat erectile dysfunction. Which of the following statements by the client indicates an understanding of the teaching?
- A. This medication will protect me from sexually transmitted diseases.
- B. I will avoid eating fatty foods, while I take this medication.
- C. I should take this medication twice each day.
- D. I can expect to have constipation while I take this medication.
Correct Answer: B
Rationale: The correct answer is B. Eating fatty foods can delay the absorption of sildenafil, so avoiding them can help the medication work effectively. Choice A is incorrect because sildenafil does not protect against STDs. Choice C is incorrect as sildenafil is usually taken as needed, not twice daily. Choice D is incorrect as constipation is not a common side effect of sildenafil.

A nurse is collecting data from a client who is experiencing oxycodone toxicity. Which of the following findings should the nurse expect?
- A. Tachycardia
- B. Sedation
- C. Dilated pupils
- D. Tachypnea
Correct Answer: B
Rationale: The correct answer is B: Sedation. Oxycodone is an opioid that depresses the central nervous system, leading to symptoms such as sedation or drowsiness. This is because opioids like oxycodone bind to opioid receptors in the brain, causing a calming effect. Tachycardia (A) and dilated pupils (C) are more commonly associated with stimulant toxicity rather than opioid toxicity. Tachypnea (D) is not a typical finding in opioid toxicity as opioids tend to depress the respiratory system, causing respiratory depression instead.
Vital Signs
Laboratory Results
0800:
Client is admitted with a 3-day history of abdominal cramps and diarrhea of 4 to 5 liquid stools per day.
Client was taking amoxicillin/clavulanate 875 mg PO every 12 hr for 10 days for a respiratory tract infection. Antibiotics completed 7 days ago.
Bilateral breath sounds clear and present throughout.
Abdomen soft, distended with hyperactive bowel sounds audible in all 4 quadrants.
Stool is watery and contains mucous. Stool sent for culture.
The nurse should first address the client's ___ followed by the client's ___. (Options: Hgb level, Blood pressure, temperature, Hct level, abdominal findings, potassium level)
- A. Hgb level
- B. Blood pressure
- C. temperature
- D. Hct level
- E. abdominal findings
- F. potassium level
Correct Answer: B,F
Rationale: Action to Take: B, F; Potential Condition: Hypovolemia; Parameter to Monitor: Blood Pressure, Potassium Level.
Rationale:
1. Blood pressure should be addressed first to assess perfusion status and hemodynamic stability.
2. Potassium level should be monitored next due to potential electrolyte imbalances in hypovolemia.
3. Hgb, Hct, and abdominal findings are important but secondary to addressing perfusion and electrolyte balance.
4. Temperature is not typically the initial concern in hypovolemia.
A nurse is reinforcing teaching about phenytoin with a client who had a tonic-clonic seizure. Which of the following information should the nurse include in the teaching?
- A. Taking ginkgo biloba increases phenytoin levels.
- B. Taking phenytoin diminishes potassium levels.
- C. Monitor for gingival hyperplasia.
- D. Minimize exposure to sunlight.
Correct Answer: C
Rationale: The correct answer is C: Monitor for gingival hyperplasia. This is important because phenytoin can cause gingival overgrowth, leading to oral health issues. The nurse should educate the client to maintain good oral hygiene and visit the dentist regularly for check-ups.
A: Taking ginkgo biloba increases phenytoin levels - This statement is incorrect. Ginkgo biloba is known to interact with certain medications, but it does not specifically increase phenytoin levels.
B: Taking phenytoin diminishes potassium levels - This statement is incorrect. Phenytoin does not directly affect potassium levels. It is more likely to cause issues with calcium and vitamin D metabolism.
D: Minimize exposure to sunlight - This statement is incorrect. While some antiepileptic medications can increase sensitivity to sunlight, phenytoin is not typically associated with this side effect.
Overall, monitoring for gingival hyperplasia is the most relevant information for the client
A nurse is reviewing the medical record of a client who has a new prescription for celecoxib to treat osteoarthritis. Which of the following should the nurse recognize as a contraindication for this medication?
- A. Concurrent use of chondroitin
- B. Concurrent use of calcium supplements
- C. Penicillin allergy
- D. Sulfonamide allergy
Correct Answer: D
Rationale: The correct answer is D: Sulfonamide allergy. Celecoxib is a nonsteroidal anti-inflammatory drug (NSAID) that belongs to the sulfonamide class of medications. Patients with a known allergy to sulfonamides are at an increased risk of developing an allergic reaction to celecoxib. It is important for the nurse to recognize this contraindication to prevent potential serious adverse reactions such as anaphylaxis.
A: Concurrent use of chondroitin - This is not a contraindication for celecoxib as there is no known significant interaction between chondroitin and celecoxib.
B: Concurrent use of calcium supplements - Calcium supplements do not interact with celecoxib and are not a contraindication for its use.
C: Penicillin allergy - Penicillin allergy is not related to celecoxib use as they are different classes of medications with distinct mechanisms of action.
In summary, the correct answer is D because
A nurse is reviewing a list of current medications for a client who is starting therapy with furosemide. Which of the following medications should the nurse identify as being contraindicated?
- A. Levothyroxine
- B. Lithium carbonate
- C. Albuterol
- D. Cetirizine
Correct Answer: B
Rationale: The correct answer is B: Lithium carbonate. Furosemide can cause sodium depletion, leading to increased lithium levels and potential lithium toxicity. Levothyroxine (A) is not contraindicated with furosemide. Albuterol (C) may increase the risk of hypokalemia when used with furosemide but is not a contraindication. Cetirizine (D) does not have significant interactions with furosemide.
