Question 1 of 5
A nurse in a clinic is preparing to administer the measles, mumps, rubella (MMR) vaccine to a client. Which of the following findings should indicate to the nurse that the client has a contraindication for the MMR vaccine?
Correct Answer: C
Rationale: The correct answer is C: The client is at 9 weeks of gestation. Administering the MMR vaccine during pregnancy is contraindicated due to the theoretical risk of causing harm to the fetus. The live attenuated MMR vaccine should not be given to pregnant women as it may potentially harm the developing fetus. It is crucial to avoid administration during pregnancy to prevent any adverse effects on the unborn child.
Other options are incorrect because:
A: The client had a local reaction from a previous immunization - Local reactions to previous vaccines are not contraindications to receiving the MMR vaccine.
B: The client reports having diarrhea this morning - Diarrhea is not a contraindication for the MMR vaccine.
D: The client reports an allergy to penicillin - Allergy to penicillin is not a contraindication for the MMR vaccine.
Question 2 of 5
A nurse is reviewing the medication record of a client who has hypertension. Which of the following medications should the nurse administer to lower the client's blood pressure?
Correct Answer: B
Rationale: The correct answer is B: Amlodipine. Amlodipine is a calcium channel blocker commonly used to treat hypertension by relaxing blood vessels, reducing blood pressure. It is a first-line medication for hypertension management. Promethazine (
A) is an antihistamine, Fluconazole (
C) is an antifungal, and Phenazopyridine (
D) is a urinary analgesic, none of which are indicated for hypertension. Selecting Amlodipine aligns with evidence-based practice guidelines for hypertension management.
Question 3 of 5
A nurse is preparing to administer enoxaparin 5,000 units subcutaneous to a client. Which of the following actions should the nurse take?
Correct Answer: A
Rationale: The correct answer is A: Insert the needle at a 45° or 90° angle. When administering enoxaparin subcutaneously, the nurse should insert the needle at a 45° or 90° angle to ensure proper delivery into the subcutaneous tissue. Angling the needle helps prevent injecting the medication too deeply or too superficially, ensuring optimal absorption and effectiveness. Holding the skin taut (choice
B) is not required for subcutaneous injections. Massaging the injection site (choice
C) after administering enoxaparin is not recommended as it can cause irritation or bruising. Using a 4 cm needle (choice
D) is not specified for enoxaparin administration and may not be appropriate for all clients.
Question 4 of 5
A nurse is caring for a client who has cellulitis and is to begin antibiotic therapy. The client has a history of anaphylactic reaction to penicillin. Which of the following medications is contraindicated for this client?
Correct Answer: D
Rationale: The correct answer is D: Cephalexin. Cephalexin is a first-generation cephalosporin antibiotic, which shares a similar beta-lactam ring structure with penicillin. Due to the client's history of anaphylactic reaction to penicillin, there is a high risk of cross-reactivity and potential severe allergic reaction if cephalexin is administered.
Therefore, it is contraindicated for this client.
Choice A: Fluconazole is an antifungal medication and does not have cross-reactivity with penicillin.
Choice B: Tetracycline is a broad-spectrum antibiotic that is not related to penicillin.
Choice C: Acyclovir is an antiviral drug and is not contraindicated in a client with a penicillin allergy.
Question 5 of 5
A nurse is collecting data from a client who is taking prednisone and self-administers insulin daily. The nurse should identify that which of the following findings indicates a medication interaction?
Correct Answer: B
Rationale: The correct answer is B: Hyperglycemia. Prednisone can increase blood sugar levels, and insulin is used to lower blood sugar levels. If the client is experiencing hyperglycemia while taking both medications, it indicates a possible medication interaction. Orthostatic hypotension (
A) is not typically associated with this medication combination. Paresthesia (
C) and jaundice (
D) are not commonly related to prednisone and insulin interactions.
