1. A client's arterial blood gas results show a pH of 7.3 and a PaCO2 of 50 mm Hg. The client is experiencing which of the following acid-base imbalances?

• A. Metabolic acidosis
• B. Metabolic alkalosis
• C. Respiratory acidosis
• D. Respiratory alkalosis

Correct answer: C

Rationale: In respiratory acidosis, there is an excess of carbon dioxide (PaCO2 > 45 mm Hg) leading to a decrease in pH (<7.35). The given values of a pH of 7.3 and PaCO2 of 50 mm Hg indicate respiratory acidosis. Metabolic acidosis involves a primary decrease in bicarbonate levels with a compensatory decrease in PaCO2 to maintain balance. Metabolic alkalosis is characterized by elevated pH and bicarbonate levels. Respiratory alkalosis is marked by low PaCO2 and increased pH levels.

2. A client is receiving discharge teaching after a total hip replacement. Which statement by the client indicates a need for further teaching?

• A. I will avoid crossing my legs when sitting.
• B. I can sleep on my side as long as I use a pillow between my legs.
• C. I will avoid bending at the waist to pick things up.
• D. I can bend down to tie my shoes after 2 weeks.

Correct answer: D

Rationale: After a total hip replacement, clients should avoid bending at the waist past 90 degrees for at least 6 weeks to prevent dislocation of the hip prosthesis. Bending down to tie shoes involves significant hip flexion and should be avoided during the initial postoperative period to ensure proper healing and reduce the risk of complications.

3. A healthcare professional auscultates a harsh hollow sound over a client's trachea & larynx. Which action should the healthcare professional take first?

• A. Document findings.
• B. Administer O2 therapy.
• C. Position client in high-Fowler's position.
• D. Administer prescribed albuterol.

Correct answer: A

Rationale: The healthcare professional has identified bronchial breath sounds, which are normal findings over the trachea & larynx, characterized by harsh, hollow, tubular, and blowing sounds. The appropriate initial action for the healthcare professional is to document these normal findings. Oxygen therapy, administering albuterol, or repositioning the client is unnecessary as this finding does not indicate a need for intervention.

4. A client with tuberculosis is starting combination drug therapy. Which of the following medications should the nurse NOT plan to administer?

• A. Rifampin
• B. Isoniazid
• C. Acyclovir
• D. Pyrazinamide

Correct answer: C

Rationale: Acyclovir is an antiviral medication used to treat herpes virus infections, not tuberculosis. Rifampin, Isoniazid, and Pyrazinamide are all commonly used in the treatment of tuberculosis. Therefore, the nurse should not plan to administer Acyclovir to a client with tuberculosis.

5. A client with chronic obstructive pulmonary disease (COPD) is being assessed by a nurse. Which finding does the nurse expect?

• A. Increased anteroposterior (AP) chest diameter
• B. Decreased respiratory rate
• C. Weight gain
• D. Productive cough with yellow sputum

Correct answer: A

Rationale: Clients with COPD commonly develop a barrel chest, characterized by an increased anteroposterior diameter of the chest. This change is due to chronic air trapping and hyperinflation of the lungs. A decreased respiratory rate, weight gain, and productive cough with yellow sputum are not typical findings in COPD. Instead, COPD patients often present with an increased respiratory rate, weight loss, and a chronic cough with sputum production.
