Which symptoms will be most important for the nurse to assess for early signs of respiratory distress in the patient who has been given a neuromuscular-blocking agent?

Dyspnea, increased respiratory rate, and cyanosis.

Restlessness, anxiety, and lethargy.

Nasal ﬂaring and retraction of intercostal muscles.

Pallor, stridor, and diaphoresis.

Answer and Explanation

The Correct Answer is A

Dyspnea (difficulty breathing), an increased respiratory rate, and cyanosis (bluish discolouration of the skin and mucous membranes due to lack of oxygen) are early signs of respiratory distress that the nurse should assess for in a patient who has been given a neuromuscular-blocking agent. These medications can cause respiratory depression and compromise the patient’s ability to breathe eﬀectively.

Correct Answer is A

Explanation

Prophylactic antibiotics are antibiotics given to prevent an infection from occurring. They are often used in situations where there is a high risk of infection, such as during surgery or dental procedures. However, prophylactic antibiotics are not recommended for all clients.

Option b is a situation where prophylactic antibiotics are recommended. Clients with prosthetic heart valves are at an increased risk of developing infective endocarditis (infection of the heart lining) during dental procedures due to the risk of bacteria entering the bloodstream.

Option c is another situation where prophylactic antibiotics may be used. Clients who have had an emergency cesarean section are at an increased risk of developing post-operative infections, and prophylactic antibiotics may be given to prevent this.

Option d is also a situation where prophylactic antibiotics may be used. Total hip arthroplasty is a surgical procedure that involves replacing the hip joint with a prosthesis. Clients who undergo this procedure are at an increased risk of developing a surgical site infection, and prophylactic antibiotics may be given to prevent this.

Option a, on the other hand, does not warrant prophylactic antibiotics. A fever of unknown origin does not necessarily indicate an infection, and antibiotics should only be given when there is a confirmed bacterial infection. Inappropriate use of antibiotics can lead to antibiotic resistance and other adverse eﬀects.

A. Headache B. Constipation C. Bradycardia D. Hypertension

Correct Answer is B

Explanation

The correct answer is choice b. Constipation.

Choice A rationale:

While headaches can occur with some medications, they are not a common adverse effect of diphenhydramine. Diphenhydramine's typical side effects are more related to its anticholinergic properties.

Choice B rationale:

Diphenhydramine is an antihistamine with anticholinergic effects, which can lead to dry mouth, urinary retention, and constipation as common adverse effects.

Choice C rationale:

Diphenhydramine typically does not cause bradycardia. In some cases, it may cause tachycardia (increased heart rate) rather than a slower heart rate.

Choice D rationale:

Hypertension is not typically associated with diphenhydramine. In fact, it can sometimes cause hypotension (low blood pressure) rather than high blood pressure.
