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

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.

Choice A rationale

Urinary retention refers to the inability to empty the bladder completely. While it can cause discomfort and bloating, it does not typically result in dark amber, cloudy urine with an unpleasant odor.

Choice B rationale

Urinary incontinence is the loss of bladder control, leading to the involuntary leakage of urine. It does not cause the urine to become dark amber, cloudy, or have an unpleasant odor.

Choice C rationale

A urinary tract infection (UTI) is an infection in any part of the urinary system — kidneys, bladder, urethra. Most UTIs are caused by bacteria, but they can also be caused by viruses or fungi. Symptoms of a UTI often include cloudy, dark, or strong-smelling urine.

Choice D rationale

Urinary frequency refers to needing to urinate more often than usual. It can be a symptom of many different issues, including a UTI, but on its own, it does not cause the urine to become dark amber, cloudy, or have an unpleasant odor.
