A nurse is preparing to administer a 5 mg IV bolus of metoprolol to a patient for heart rate control.

The available metoprolol injection is 1 mg/mL. How many mL should the nurse administer per dose?

(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Choice A rationale

Polycystic ovarian syndrome is a hormonal disorder common among women of reproductive age. While it can lead to several complications, it does not significantly increase the risk of sepsis.

Choice B rationale

Cancer and certain treatments for cancer can weaken the immune system, increasing the risk of infections that could lead to sepsis.

Choice C rationale

Kallmann’s syndrome is a genetic condition that affects the production of a hormone involved in sexual development. It does not significantly increase the risk of sepsis.

Choice D rationale

Addison’s disease affects the adrenal glands and can disrupt the balance of hormones in the body, but it does not significantly increase the risk of sepsis.

Choice A rationale

Intussusception is a serious condition in which part of the intestine slides into an adjacent part of the intestine. This “telescoping” often blocks food or fluid from passing through.

Intussusception also cuts off the blood supply to the part of the intestine that’s affected. It can lead to a tear in the bowel (perforation), infection and death of bowel tissue.

Choice B rationale

Wilms’ tumor is a rare kidney cancer that primarily affects children. Also known as nephroblastoma, Wilms’ tumor is the most common cancer of the kidneys in children. Wilms’ tumor most often affects children ages 3 to 4 and becomes much less common after age 52.

Choice C rationale

Pyloric stenosis is a condition that affects infants between birth and 6 months of age and causes forceful vomiting that can lead to dehydration. It’s the second most common reason why newborns have surgery. Pyloric stenosis can be fixed with a surgical procedure called pyloromyotomy.

Choice D rationale

Nephrotic syndrome is a kidney disorder that causes your body to excrete too much protein in your urine. Nephrotic syndrome is usually caused by damage to the clusters of small blood vessels in your kidneys that filter waste and excess water from your blood.
