1. A healthcare professional is reviewing the medical record of a client who has a new prescription for ceftriaxone. The healthcare professional should identify which of the following findings as a contraindication to this medication?
- A. Seizure disorder
- B. Hypertension
- C. Penicillin allergy
- D. Hyperlipidemia
Correct answer: C
Rationale: The correct answer is C: Penicillin allergy. Penicillin allergy is a contraindication for ceftriaxone because both medications are beta-lactam antibiotics. Seizure disorder (choice A), hypertension (choice B), and hyperlipidemia (choice D) are not contraindications for ceftriaxone and do not directly affect the use of this antibiotic.
2. You are caring for a patient who is being treated on the oncology unit with a diagnosis of lung cancer with bone metastases. During your assessment, you note the patient complains of a new onset of weakness with abdominal pain. Further assessment suggests that the patient likely has a fluid volume deficit. You should recognize that this patient may be experiencing what electrolyte imbalance?
- A. Hypernatremia
- B. Hypomagnesemia
- C. Hypophosphatemia
- D. Hypercalcemia
Correct answer: Hypercalcemia
Rationale:
3. A client has an infection and a prescription for gentamicin intermittent IV bolus every 8 hr. A peak and trough is required with the next dose. Which of the following actions should be taken to obtain an accurate gentamicin serum level?
- A. Draw a trough level immediately prior to administering the medication and a peak level 30 min after the dose.
- B. Draw a peak level 90 min prior to administering the medication and a trough level 90 min after the dose.
- C. Draw a trough level immediately prior to administering the medication and a peak level 30 min after the dose.
- D. Draw a peak level at 0900 and a trough level at 2100.
Correct answer: C
Rationale: To obtain an accurate gentamicin serum level, the trough should be drawn immediately before administering the medication, and the peak level should be drawn 30 minutes after the dose. This timing allows for the assessment of the lowest and highest drug concentrations in the bloodstream, ensuring therapeutic levels are achieved while minimizing the risk of toxicity. Choice A is correct as it follows this timing protocol. Choices B and D have incorrect timing for peak and trough levels, which would not provide an accurate representation of the drug's concentration in the bloodstream.
4. In teaching the parent of a newly diagnosed 2-year-old child with pyelonephritis related to vesicoureteral reflux (VUR), the nurse should include which information?
- A. Limit fluids to reduce reflux.
- B. Give cranberry juice twice a day.
- C. Have siblings examined for VUR.
- D. Surgery is indicated to reverse scarring.
Correct answer: C
Rationale: Siblings should be examined for VUR as it can run in families, and early detection can prevent complications. Limiting fluids is not advisable, and cranberry juice is not effective in preventing VUR. Surgery is usually not indicated for scarring reversal.
5. What is the pathophysiologic process responsible for the decreased glomerular filtration rate in a patient with acute glomerulonephritis?
- A. Decreased renal-induced constriction of the renal arteries
- B. Immune complex deposition, increased capillary permeability, and cellular proliferation
- C. Necrosis of 70% or more of the nephrons secondary to increased kidney interstitial hydrostatic pressure
- D. Scar tissue formation throughout the proximal convoluted tubule secondary to toxin-induced collagen synthesis
Correct answer: B
Rationale: The correct answer is B: Immune complex deposition, increased capillary permeability, and cellular proliferation. Acute glomerulonephritis is characterized by inflammation of the glomeruli in the kidneys. This inflammation leads to the deposition of immune complexes, increased capillary permeability, and cellular proliferation, which collectively contribute to a decreased glomerular filtration rate. Choice A is incorrect as decreased renal-induced constriction of the renal arteries would not directly result in decreased glomerular filtration rate. Choice C is incorrect as necrosis of nephrons due to increased kidney interstitial hydrostatic pressure would affect kidney function differently. Choice D is incorrect as scar tissue formation in the proximal convoluted tubule due to toxin-induced collagen synthesis is not a typical feature of acute glomerulonephritis.
