Nursing Elites

1. A nurse is teaching a newly licensed nurse about contraindications to ceftriaxone. The nurse should include that a severe allergy to which of the following medications is a contraindication to ceftriaxone?

• A. Gentamicin
• B. Clindamycin
• C. Piperacillin
• D. Sulfamethoxazole-trimethoprim

Correct answer: C

Rationale: The correct answer is C. Ceftriaxone, a cephalosporin antibiotic, has a cross-sensitivity with penicillin antibiotics like piperacillin. Therefore, a severe allergy to penicillin or penicillin-related antibiotics would be a contraindication to ceftriaxone. Choices A, B, and D are incorrect because they are not associated with a known cross-sensitivity with ceftriaxone.

2. A nurse is preparing to administer iron dextran IV to a client. Which of the following actions should the nurse plan to take?

• A. Administer a small test dose before giving the full dose
• B. Infuse the medication over 30 seconds
• C. Monitor client closely for hypertension
• D. Administer cyanocobalamin as an antidote if toxicity occurs

Correct answer: A

Rationale: The correct action the nurse should plan to take when preparing to administer iron dextran IV is to administer a small test dose before giving the full dose. This is done to assess for any allergic reactions that the client may have to the medication. Choice B is incorrect because iron dextran should be infused slowly over a longer period, typically over 1-2 hours to reduce the risk of adverse reactions. Choice C is incorrect because iron dextran administration is more commonly associated with hypotension rather than hypertension. Choice D is incorrect because cyanocobalamin is not used as an antidote for iron dextran toxicity; instead, treatment for iron toxicity may involve supportive care, chelation therapy, or in severe cases, iron antidotes like deferoxamine.

3. A healthcare professional is planning to administer diltiazem via IV bolus to a client who has atrial fibrillation. When assessing the client, the healthcare professional should recognize that which of the following findings is a contraindication to the administration of diltiazem?

• A. Hypotension
• B. Tachycardia
• C. Decreased level of consciousness
• D. History of diuretic use

Correct answer: A

Rationale: Diltiazem, a calcium channel blocker, can cause hypotension. Administering it to a client who already has hypotension could exacerbate this condition. Therefore, hypotension is a contraindication to the administration of diltiazem. Incorrect Choices: B) Tachycardia is not a contraindication for administering diltiazem in atrial fibrillation as it is commonly used to control the heart rate. C) Decreased level of consciousness may require evaluation but is not a direct contraindication to diltiazem administration. D) History of diuretic use is not a contraindication if the client is not currently experiencing hypotension.

4. A nurse is reviewing the laboratory values for a client who is receiving a continuous IV heparin infusion and has an aPTT of 90 seconds. Which of the following actions should the nurse prepare to take?

• A. Administer vitamin K
• B. Reduce the infusion rate
• C. Give the client a low-dose aspirin
• D. Request an INR

Correct answer: B

Rationale: An aPTT of 90 seconds is elevated, indicating a risk of bleeding due to excessive anticoagulation. The appropriate action is to reduce the infusion rate of heparin to prevent further complications. Administering vitamin K is not indicated for an elevated aPTT due to heparin therapy. Giving the client a low-dose aspirin can further increase the risk of bleeding when combined with heparin. Requesting an INR is not necessary for monitoring heparin therapy; aPTT is the more specific test for assessing heparin's therapeutic effect. Therefore, the correct action for the nurse to prepare to take is to reduce the infusion rate of heparin.

5. A nurse is caring for an older adult client who has a new prescription for amitriptyline to treat depression. Which of the following diagnostic tests should the nurse plan to perform prior to starting the client on this medication?

• A. Hearing examination
• B. Glucose tolerance test
• C. Electrocardiogram
• D. Pulmonary function tests

Correct answer: C

Rationale: The correct answer is C: Electrocardiogram. Amitriptyline can cause cardiac arrhythmias, so an electrocardiogram is necessary before starting treatment. A hearing examination (choice A) is not required before initiating amitriptyline. A glucose tolerance test (choice B) is not indicated for starting this medication. Pulmonary function tests (choice D) are not necessary before initiating amitriptyline for depression.
