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.)

The condition that poses the greatest risk to the newborn is Meconium aspiration syndrome due to color of amniotic fluid.

Meconium aspiration syndrome is a serious condition that can occur when a newborn inhales a mixture of meconium (the first stool) and amniotic fluid into the lungs around the time of delivery. The dark brown-greenish color of the amniotic fluid indicates the presence of meconium, which increases the risk of this condition.

Choice A rationale

After a total laryngectomy, patients may have difficulty swallowing fluids due to changes in the anatomy of the throat.

Choice B rationale

It is not accurate to say that it is no longer possible for the patient to choke on or aspirate food after a total laryngectomy. While the risk of aspiration is reduced because the airway and digestive tract are separated, the patient can still experience choking on food if it is not properly swallowed.

Choice C rationale

Adding a thickener to liquids can help prevent aspiration, but this is typically more relevant for patients with dysphagia or other swallowing disorders, not specifically for patients post- laryngectomy.

Choice D rationale

Tucking the chin when swallowing, also known as the chin-tuck maneuver, can help prevent aspiration by narrowing the entrance to the airway. This can be a useful technique for patients after a laryngectomy.
