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?

Promethazine

Amlodipine

Fluconazole

Phenazopyridine

Answer and Explanation

The Correct Answer is B

A. Promethazine. Promethazine is an antihistamine used to treat nausea, vomiting, and allergic reactions. It does not have antihypertensive properties and does not lower blood pressure. Instead, it has sedative effects and is commonly used for motion sickness or as a preoperative medication.

B. Amlodipine. Amlodipine is a calcium channel blocker that lowers blood pressure by relaxing blood vessels and improving blood flow. It is commonly prescribed for hypertension and angina, as it reduces vascular resistance and decreases the workload on the heart. Clients taking amlodipine should be monitored for hypotension, edema, and dizziness.

C. Fluconazole. Fluconazole is an antifungal medication used to treat fungal infections such as candidiasis. It does not affect blood pressure regulation and is not used for managing hypertension. However, it can interact with certain medications, so monitoring for drug interactions is important.

D. Phenazopyridine. Phenazopyridine is a urinary analgesic used to relieve symptoms of urinary tract infections (UTIs), such as burning and pain during urination. It does not lower blood pressure and has no effect on cardiovascular function. Clients should be advised that this medication can cause orange discoloration of the urine.

Correct Answer is ["6"]

Explanation

Calculate the total daily dose:

Total daily dose (mg) = Weight (kg) x Dosage (mg/kg/day)

=14.9 kg x 40 mg/kg/day

= 596 mg/day

Calculate the dose per administration (divided into two doses):

Dose per administration (mg) = Total daily dose (mg) / Number of doses

= 596 mg/day / 2 doses

= 298 mg/dose

Calculate the volume to administer per dose:

Volume (mL) = Desired dose (mg) / Available concentration (mg/mL)

Available concentration = 250 mg / 5 mL

= 50 mg/mL

Volume (mL) = 298 mg / 50 mg/mL

= 5.96 mL/dose

Round to the nearest whole number:

5.96 mL is 6 mL/dose

A. Baker's yeast B. Nuts C. Wheat D. Egg yolk

Correct Answer is A

Explanation

A. Baker's yeast. The hepatitis B vaccine is contraindicated in individuals with a severe allergy to baker’s yeast. This is because the vaccine is produced using Saccharomyces cerevisiae (baker’s yeast), which can trigger an allergic reaction in susceptible individuals. Symptoms of a yeast allergy may include rash, difficulty breathing, and anaphylaxis, requiring the vaccine to be withheld and an alternative plan considered.

B. Nuts. Nut allergies are not related to the hepatitis B vaccine, as it does not contain nut-derived ingredients. While nut allergies can be severe and cause anaphylaxis, they do not pose a specific risk in the administration of this vaccine. Therefore, the presence of a nut allergy alone does not require withholding the immunization.

C. Wheat. A wheat allergy is not a contraindication for the hepatitis B vaccine. Wheat allergies primarily cause reactions to gluten-containing foods or products but do not have any connection to the components used in the production of the vaccine. The vaccine can be safely administered to individuals with wheat allergies.

D. Egg yolk. While some vaccines, such as the influenza vaccine, may be derived from egg proteins, the hepatitis B vaccine is not produced using egg-based components. An allergy to egg yolk does not pose a risk for adverse reactions to this vaccine, so it should not be withheld in individuals with an egg allergy.
