Nursing Elites

1. Intravenous heparin therapy is prescribed for a client. While implementing this prescription, a nurse ensures that which of the following medications is available on the nursing unit?

• A. Protamine sulfate
• B. Potassium chloride
• C. Phytonadione (vitamin K)
• D. Aminocaproic acid (Amicar)

Correct answer: A

Rationale: Protamine sulfate is the antidote for heparin, working to reverse its effects in case of excessive bleeding. It should be readily available when administering heparin to manage any potential bleeding complications effectively. Potassium chloride is not the antidote for heparin and is typically used to correct low potassium levels. Phytonadione (vitamin K) is used to reverse the effects of warfarin, not heparin. Aminocaproic acid (Amicar) is used to treat or prevent excessive bleeding but is not the antidote for heparin.

2. A client is taking phenytoin (Dilantin) for seizure control, and a sample for a serum drug level is drawn. Which of the following indicates a therapeutic serum drug range?

• A. 5 to 10 mcg/mL
• B. 10 to 20 mcg/mL
• C. 20 to 30 mcg/mL
• D. 30 to 40 mcg/mL

Correct answer: B

Rationale: The correct therapeutic serum drug level range for phenytoin (Dilantin) is 10 to 20 mcg/mL. This range is considered optimal for seizure control while minimizing the risk of toxicity. Monitoring drug levels helps ensure that the client is within the therapeutic range for effective treatment.

3. While assisting in caring for a pregnant client receiving intravenous magnesium sulfate for preeclampsia management, a nurse notes the client's absent deep tendon reflexes. What determination should the nurse make based on this data?

• A. The magnesium sulfate is effective.
• B. The infusion rate needs to be increased.
• C. The client is experiencing cerebral edema.
• D. The client is experiencing magnesium toxicity.

Correct answer: D

Rationale: When a pregnant client receiving intravenous magnesium sulfate for preeclampsia management exhibits absent deep tendon reflexes, this indicates magnesium toxicity. Magnesium toxicity can occur as a complication of magnesium sulfate therapy, leading to suppressed reflexes. It is crucial for the nurse to recognize this sign promptly and report it to prevent further complications or harm to the client.

4. Phenazopyridine hydrochloride (Pyridium) is prescribed for a client for symptomatic relief of pain resulting from a lower urinary tract infection. The nurse reinforces to the client:

• A. To take the medication after meals
• B. To take the medication before meals
• C. To discontinue the medication if a headache occurs
• D. That a reddish-orange discoloration of the urine may occur

Correct answer: D

Rationale: The nurse should instruct the client that a reddish-orange discoloration of urine may occur. The nurse should also educate the client that this discoloration can stain fabric. It is recommended to take the medication after meals to reduce the possibility of gastrointestinal upset. While a headache is an occasional side effect of the medication, it does not warrant discontinuation of the medication.

5. A client taking fexofenadine (Allegra) is scheduled for allergy skin testing and tells the nurse in the healthcare provider's office that a dose was taken this morning. The nurse determines that:

• A. The client should reschedule the appointment.
• B. A lower dose of allergen will need to be injected.
• C. A higher dose of allergen will need to be injected.
• D. The client should have the skin test read a day later than usual.

Correct answer: A

Rationale: Fexofenadine, an antihistamine, can cause false-negative readings in allergy skin testing and should be discontinued 3 days prior. Therefore, the client should reschedule the appointment to ensure accurate test results.
