A nurse on a Medical-Surgical unit is preparing to administer an intramuscular injection to a client. Which of the following sites can the nurse use? (Select all that apply.).

Choice A rationale:

Asthma - Asthma is a chronic respiratory condition characterized by bronchoconstriction, inflammation, and increased mucus production. It does not typically present with absent breath sounds, deviation of the trachea, or hyperresonant percussion sounds. Wheezing is a common finding in asthma.

Choice B rationale:

Pneumothorax - This is the correct choice. The scenario describes classic signs of a tension pneumothorax, which is a medical emergency. The tracheal deviation, absence of breath sounds, and hyperresonant percussion note on the affected side are indicative of air accumulation in the pleural space, leading to lung collapse and displacement of mediastinal structures.

Choice C rationale:

Atelectasis - Atelectasis refers to the collapse or incomplete expansion of a lung or part of a lung. It can lead to decreased breath sounds on auscultation but does not usually cause tracheal deviation or hyperresonance on percussion. It is not the best fit for the described signs.

Choice D rationale:

Pneumonia - Pneumonia is an infection of the lung tissue that can cause symptoms like fever, cough, and productive sputum. Breath sounds may be diminished over the affected area due to consolidation, but the absence of breath sounds, tracheal deviation, and hyperresonance point more strongly toward a pneumothorax in this case.

Choice A rationale:

Applying the pulse oximeter probe to the toe is not the most appropriate location. While toe measurements can be used, the fingers are more commonly used due to their accessibility and accuracy. Edema in the hands could affect the accuracy of readings.

Choice B rationale:

The nurse should apply the pulse oximeter probe to the earlobe. This choice is correct because the earlobe is a well-vascularized and easily accessible area that provides accurate oxygen saturation measurements. Thickened toenails and edema of the hands might compromise readings in those locations.

Choice C rationale:

Applying the pulse oximeter probe to a skin fold is not a recommended site for oxygen saturation measurement. While there are various sites where pulse oximeters can be applied, the earlobe and finger are more suitable due to their consistent blood flow and accessibility.

Choice D rationale:

While applying the pulse oximeter probe to the finger is a common and acceptable practice, in this scenario, edema of the hands could affect the accuracy of the readings. The earlobe is a better choice as it is less likely to be affected by edema and can provide accurate readings.
