An assistive personnel (AP) asks a nurse what precautions he should take when measuring the vital signs of a client who has pneumonia. Which of the following responses should the nurse make?

"Wear a mask when entering the client's room."

"Gloves are not necessary if you wash your hands well."

"Place a mask on the client when you check her vital signs."

"Wear a gown whenever you come in close contact with the client."

Answer and Explanation

The Correct Answer is A

A.   Wearing a mask helps prevent the spread of respiratory droplets that may contain infectious pathogens, such as those causing pneumonia. It protects both the client from potential pathogens carried by the AP and the AP from potential exposure to the client's respiratory secretions.

B.   Gloves should be worn when there is a risk of contact with the client's body fluids, including respiratory secretions, to prevent transmission of infectious agents. Hand hygiene (washing hands well) is important but does not replace the need for gloves in situations where there is a risk of exposure to bodily fluids.
C.   Placing a mask on the client would not typically be required unless the client is coughing excessively and the mask is intended to contain respiratory droplets. However, the focus of precautions should primarily be on protecting the AP.
D.   Wearing a gown may be necessary if there is a risk of contamination with respiratory secretions or if the AP anticipates contact with the client's body fluids. However, it is not specifically required for routine vital sign measurement unless there is visible contamination or extensive contact with the client's secretions.

Correct Answer is D

Explanation

A. Hypercalcemia can lead to muscle weakness and fatigue rather than hypotonicity. High calcium levels affect neuromuscular function, potentially causing muscle weakness and decreased muscle tone rather than increased flaccidity.
B. Chvostek's sign is a clinical sign of hypocalcemia, not hypercalcemia. It is characterized by facial muscle twitching in response to tapping the facial nerve just anterior to the ear. Therefore, a positive Chvostek's sign would not be expected in hypercalcemia.
C. Hypercalcemia can cause gastrointestinal disturbances such as constipation rather than diarrhea. High calcium levels can lead to decreased smooth muscle contractility in the intestines, resulting in constipation rather than increased motility leading to diarrhea.
D. Hypercalcemia can lead to a variety of cardiovascular effects, including arrhythmias. Tachycardia can occur as a result of increased sensitivity of the heart to catecholamines and altered electrical conductivity in hypercalcemia.

A. Avoid applying pressure to the tragus of the ear. B. Don sterile gloves to instill the medication C. Pull the pinna upward and backward. D. Chill the otic solution prior to administration.

Correct Answer is C

Explanation

A. The tragus is a small projection of cartilage in front of the ear canal. Applying gentle pressure to the tragus after instilling ear drops helps to facilitate the passage of the drops into the ear canal. This action should not be avoided; rather, it is recommended to enhance the delivery of the medication.
B. Sterile gloves are not typically necessary for instilling ear drops unless the client has an open or infected ear canal. Using clean, non-sterile gloves or practicing proper hand hygiene is sufficient to maintain cleanliness during the procedure.
C. For an adult client, pulling the pinna (outer ear) upward and backward helps to straighten the ear canal. This allows the drops to flow easily into the ear canal rather than pooling in the outer ear or leaking out. This technique ensures that the medication reaches the target area effectively.
D. Chilling otic (ear) solutions is not recommended unless specifically instructed by the healthcare provider for therapeutic reasons (e.g., to soothe ear pain or inflammation). Cold solutions can cause discomfort or dizziness when instilled into the ear. Therefore, otic solutions are typically administered at room temperature to avoid these adverse effects.
