A client is being cared for by a nurse 2 hours after admission. The client has an SaO2 of 91%, exhibits audible wheezes, and is using accessory muscles when breathing. Which of the following classes of medication should the nurse expect to administer?

Correct Answer: D

Rationale: The client's presentation with an SaO2 of 91%, audible wheezes, and use of accessory muscles indicates respiratory distress, likely due to bronchoconstriction. Beta2 agonists are the appropriate class of medications to administer in this situation as they act as bronchodilators, helping to relieve the bronchoconstriction and improve airflow to the lungs. Antibiotics, beta-blockers, and antivirals are not indicated for this client's respiratory distress symptoms.

Correct Answer: B

Rationale: In a client with left homonymous hemianopsia, there is a loss of vision on the right side of both eyes. Placing the bedside table on the right side of the bed ensures that essential items are within the client's field of vision, minimizing the risk of injury or accidents. Teaching the client to scan to the right and orienting them using the clock method may be helpful strategies, but placing the bedside table on the right side of the bed is a more direct and immediate intervention to enhance the client's safety and independence.

Correct Answer: B

Rationale: A Venturi mask is the most appropriate choice for delivering a precise amount of oxygen to a client with dyspnea. Unlike other oxygen delivery devices, the Venturi mask allows for accurate oxygen concentration delivery by controlling the amount of air entrained. This feature is crucial in ensuring the client receives the prescribed oxygen concentration, especially in cases where precise oxygen delivery is required.

Correct Answer: B

Rationale: During a thoracentesis procedure, the focus is on draining fluid or air from the pleural space. An incentive spirometer, which helps improve lung function, is not a necessary supply for this specific procedure. Oxygen equipment, pulse oximeter for monitoring oxygen saturation levels, and sterile dressing for wound care may be needed during or after the procedure.

Correct Answer: A

Rationale: Positioning the client in an upright position, leaning over the bedside table helps to facilitate access to the thoracic cavity during the thoracentesis procedure. This position allows for easier identification and access to the insertion site. Explaining the procedure to the client is important, but positioning is the priority. Obtaining ABGs is not directly related to the thoracentesis procedure. Administering benzocaine spray is not a standard practice before a thoracentesis.

Correct Answer: D

Rationale: During the removal of a chest tube, instructing the client to perform the Valsalva maneuver is essential. This maneuver involves holding the breath and bearing down, which helps prevent air from entering the pleural space during tube removal, reducing the risk of pneumothorax. Instructing the client to lie on their left side, use the incentive spirometer, or cough at regular intervals is not appropriate during the chest tube removal process.

Correct Answer: B

Rationale: Avocados contain high levels of tyramine, which can cause a hypertensive crisis when consumed with phenelzine, a monoamine oxidase inhibitor (MAOI). It is essential for clients taking MAOIs to avoid foods rich in tyramine to prevent dangerous interactions and potential health risks.

Correct Answer: C

Rationale: A client who was vaccinated for pneumococcus and influenza 6 months ago would have a reduced risk of developing pneumonia compared to those who have not been vaccinated. Vaccination helps protect individuals from specific pathogens, thereby lowering the risk of infection. Clients with dysphagia, AIDS, or a closed head injury and receiving ventilation are at higher risk for pneumonia due to compromised immunity, respiratory function, or protective airway reflexes, respectively.

Correct Answer: C

Rationale: Patients who have experienced a left-hemispheric stroke may exhibit symptoms of agnosia, which is the inability to recognize familiar objects or people. This occurs due to damage to the right hemisphere of the brain, which is responsible for visual and spatial perception. Impulse control difficulty, poor judgment, and loss of depth perception are not typically associated with left-hemispheric strokes.
