A nurse is assessing a client who has pneumonia. Which of the following manifestations should the nurse expect?

Crackles.

Crepitus.

Stridor.

Decreased fremitus.

Answer and Explanation

The Correct Answer is A

Choice A rationale:

Crackles are adventitious lung sounds that can be heard on auscultation and are commonly associated with pneumonia. They are caused by the movement of air through fluid-filled or collapsed alveoli, indicating inflammation and infection in the lungs.

Choice B rationale:

Crepitus is a different respiratory finding and is not typically associated with pneumonia. Crepitus is a crackling or grating sensation that can be felt under the skin, often caused by subcutaneous emphysema or gas trapped in the tissues, not within the lungs.

Choice C rationale:

Stridor is a harsh, high-pitched sound heard during inspiration and is usually indicative of upper airway obstruction, not pneumonia. It can be caused by conditions such as croup or anaphylaxis.

Choice D rationale:

Decreased fremitus is not a specific manifestation of pneumonia. Fremitus is the vibration felt when the patient speaks and is transmitted through the chest wall. In pneumonia, increased fremitus may be observed due to the consolidation of lung tissue with fluid or pus, not decreased fremitus.

Correct Answer is C

Explanation

Choice A rationale:
10 mL/hr would be the correct infusion rate if the client was receiving the entire 10 mEq of potassium chloride in a 100 mL solution over 1 hour. However, the question asks for the rate at which to administer 10 mEq over 1 hour, which means the total volume should be 100 mL/hr.
Choice B rationale:
50 mL/hr would be the correct infusion rate if the client was receiving the entire 10 mEq of potassium chloride in a 100 mL solution over 2 hours. However, the question specifies 1 hour, so the rate should be higher.
Choice C rationale:
This is the correct answer. To administer 10 mEq of potassium chloride in 100 mL over 1 hour, the infusion pump should be set to deliver 100 mL/hr.
Choice D rationale:
500 mL/hr would be the correct infusion rate if the client was receiving the entire 10 mEq of potassium chloride in a 100 mL solution over 10 minutes (1/6th of an hour). However, the question specifies 1 hour, so the rate should be much lower.

A. The client's bed has a three-prong plug attached to the electrical cord. B. A protective cover is inserted into an unused outlet. C. An IV pump is plugged into an outlet near a sink. D. An electrical cord is coiled and secured to the floor.

Correct Answer is C

Explanation

Choice A rationale:

A three-prong plug attached to the electrical cord of the client's bed is not a safety hazard. It is a standard plug type used in many electrical devices and poses no immediate danger if properly installed.

Choice B rationale:

Inserting a protective cover into an unused outlet is actually a safety measure to prevent electrical accidents. It is not a hazard but a recommended practice.

Choice C rationale:

Plugging an IV pump into an outlet near a sink is a safety hazard. Water and electricity are a dangerous combination, and any spill or leakage around the outlet could lead to electrical shock or damage to the equipment.

Choice D rationale:

Coiling and securing an electrical cord to the floor can be a potential tripping hazard, but it is not as hazardous as having an electrical device near a sink. Tripping hazards can cause falls, while the combination of water and electricity is more likely to cause serious injuries.
