1. A client has a Cerebrospinal fluid infection with gram-negative bacteria. Which of the following Cephalosporin antibiotics should be administered IV to treat this infection?
- A. Cefaclor
- B. Cefazolin
- C. Cefepime
- D. Cephalexin
Correct answer: C
Rationale: In treating a Cerebrospinal fluid infection caused by gram-negative bacteria, Cefepime, a fourth-generation cephalosporin, is the most suitable choice due to its enhanced efficacy against gram-negative organisms in such infections. Cefaclor (Choice A) is a second-generation cephalosporin more commonly used for respiratory tract infections. Cefazolin (Choice B) is a first-generation cephalosporin often used for skin and soft tissue infections. Cephalexin (Choice D) is a first-generation cephalosporin indicated for skin and urinary tract infections, but not the optimal choice for a Cerebrospinal fluid infection with gram-negative bacteria.
2. A healthcare provider is teaching the parents of a school-age child about transdermal Methylphenidate. Which of the following instructions should the healthcare provider include?
- A. Apply one patch twice a day.
- B. Leave the patch on for 9 hours.
- C. Apply the patch to the child's waist.
- D. Use the opened tray within 6 months.
Correct answer: B
Rationale: When administering transdermal Methylphenidate, it is important to leave the patch on for 9 hours each day to ensure the medication is effective. This duration allows for proper absorption of the medication through the skin. It is crucial for parents to follow this instruction to achieve the desired therapeutic effect for their child.
3. A client has a new prescription for Spironolactone. Which of the following findings should the nurse monitor as an adverse effect?
- A. Hyperkalemia
- B. Hypoglycemia
- C. Hypocalcemia
- D. Hyponatremia
Correct answer: A
Rationale: Corrected Rationale: Spironolactone is a potassium-sparing diuretic, which can lead to hyperkalemia as an adverse effect. Hyperkalemia can result in muscle weakness and cardiac dysrhythmias, making it essential for the nurse to monitor potassium levels closely when a client is on Spironolactone. Choice B, Hypoglycemia, is incorrect because Spironolactone is not known to cause low blood sugar levels. Choice C, Hypocalcemia, and Choice D, Hyponatremia, are also incorrect as Spironolactone is not associated with decreased levels of calcium or sodium.
4. While providing an Angiotensin-converting enzyme (ACE) inhibitor, the patient asks what the action of the drug is. As a healthcare provider, you explain that the action of an ACE inhibitor is:
- A. To lower blood pressure by blocking the conversion of angiotensin I to vasoconstrictor angiotensin II
- B. To inhibit reabsorption of sodium back into the body, ultimately increasing urine output and lowering blood pressure
- C. To decrease heart rate and blood pressure by competing with Beta1 and Beta2 receptors in the heart and lungs
- D. To lower blood glucose by stimulating the release of insulin
Correct answer: A
Rationale: ACE inhibitors lower blood pressure by blocking the conversion of angiotensin I to vasoconstrictor angiotensin II. Angiotensin II is a potent vasoconstrictor, and by inhibiting its formation, ACE inhibitors help dilate blood vessels, reduce blood pressure, and decrease the workload on the heart. Choice B is incorrect as it describes the mechanism of action of diuretics, not ACE inhibitors. Choice C is incorrect as it refers to the action of beta-blockers, not ACE inhibitors. Choice D is incorrect as it describes the mechanism of action of antidiabetic medications, not ACE inhibitors.
5. A client with Preeclampsia is receiving Magnesium Sulfate IV continuous infusion. Which of the following findings should the nurse report to the provider?
- A. 2+ deep tendon reflexes
- B. 2+ pedal edema
- C. 24 mL/hr urinary output
- D. Respirations 12/min
Correct answer: C
Rationale: In a client receiving Magnesium Sulfate IV continuous infusion for Preeclampsia, a urinary output less than 25 to 30 mL/hr is indicative of magnesium sulfate toxicity and should be promptly reported to the provider for further evaluation and management. Therefore, the correct answer is C. Option A, 2+ deep tendon reflexes, are expected findings in a client receiving magnesium sulfate and do not require immediate reporting. Option B, 2+ pedal edema, is a common symptom of preeclampsia and typically does not require immediate intervention. Option D, respirations 12/min, are within the normal range and do not indicate an immediate need for reporting to the provider.
