Nursing Elites

1. Blood for arterial blood gas determinations is drawn from a client with pneumonia, and testing reveals a pH of 7.45, PCO2 of 30 mm Hg, and HCO3 of 19 mEq/L. The nurse interprets these results as indicative of:

• A. Compensated metabolic acidosis
• B. Compensated respiratory alkalosis
• C. Uncompensated metabolic alkalosis
• D. Uncompensated respiratory acidosis

Correct answer: B

Rationale: The correct answer is 'Compensated respiratory alkalosis.' In this case, the client's pH is within the normal range (7.35-7.45), indicating compensation. The low PCO2 (30 mm Hg) suggests respiratory alkalosis, while the low HCO3 (19 mEq/L) is also consistent with a compensatory response. Therefore, the client has a primary respiratory alkalosis that is being compensated for by metabolic acidosis. Choices A, C, and D are incorrect because they do not fit the pattern of the given blood gas values, which indicate respiratory alkalosis with metabolic compensation.

2. A healthcare professional reviews the allergy list of a client scheduled for an intravenous urography. Which client allergy should prompt urgent contact with the healthcare provider?

• A. Seafood
• B. Penicillin
• C. Bee stings
• D. Red food dye

Correct answer: A

Rationale: Clients with seafood allergies should alert healthcare professionals to urgently contact the healthcare provider before an intravenous urography. The standard dyes used in this procedure can trigger severe allergic reactions in individuals with seafood allergies. Penicillin, bee stings, and red food dye allergies do not pose a direct threat during intravenous urography, making them less critical for immediate intervention.

3. The healthcare provider is caring for a patient who is receiving an intravenous antibiotic. The patient has a serum drug trough of 1.5 mcg/mL. The normal trough for this drug is 1.7 mcg/mL to 2.2 mcg/mL. What will the healthcare provider expect the patient to experience?

• A. Inadequate drug effects
• B. Increased risk of superinfection
• C. Minimal adverse effects
• D. Slowed onset of action

Correct answer: A

Rationale: A serum drug trough level below the normal range (1.7 mcg/mL to 2.2 mcg/mL) indicates that the medication concentration is insufficient to provide therapeutic effects, leading to inadequate drug effects. A low trough level does not directly correlate with an increased risk of superinfection, minimal adverse effects, or a slowed onset of action, as these are more related to the drug's concentration within the therapeutic range.

4. Four hours following surgical repair of a compound fracture of the right ulna, the nurse is unable to palpate the client's right radial pulse. Which action should the nurse take first?

• A. Notify the healthcare provider of the finding immediately.
• B. Complete a neurovascular assessment of the right hand.
• C. Elevate the client's right hand on one or two pillows.
• D. Measure the client's blood pressure and apical pulse rate.

Correct answer: B

Rationale: Completing a neurovascular assessment of the right hand is the priority in this situation. This assessment will help determine the circulation, sensation, and movement of the affected limb, ensuring there are no complications like compartment syndrome or impaired perfusion. Notifying the healthcare provider immediately (Choice A) might be necessary but should come after assessing the client's neurovascular status. Elevating the client's right hand (Choice C) can be helpful in some cases but should not precede a neurovascular assessment. Measuring the client's blood pressure and apical pulse rate (Choice D) is important but not the priority when assessing a potential vascular compromise in the limb.

5. Polyethylene glycol–electrolyte solution (GoLYTELY) is prescribed for a hospitalized client scheduled for a colonoscopy. The client begins to experience diarrhea after drinking the solution. Which action by the nurse is appropriate?

• A. Calling the physician
• B. Administering a cleansing enema
• C. Documenting the diarrhea in the medical record
• D. Giving intravenous replacement fluids in large amounts

Correct answer: C

Rationale: The correct action by the nurse in this situation is to document the diarrhea in the medical record. Polyethylene glycol–electrolyte solution (GoLYTELY) is a bowel evacuant used to cleanse the bowel before a colonoscopy. It is expected to cause mild diarrhea, which is a normal response to the medication. The diarrhea helps clear the bowel in preparation for the procedure. Calling the physician is not necessary unless there are complications. Administering a cleansing enema or giving intravenous replacement fluids in large amounts are not appropriate actions as they are not indicated for managing the expected diarrhea caused by GoLYTELY.
