Nursing Elites

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 with chronic obstructive pulmonary disease (COPD) is being taught by a healthcare provider. Which statement by the client indicates a need for further teaching?

• A. I will avoid smoking to prevent further damage to my lungs.
• B. I will eat smaller, more frequent meals to avoid feeling bloated.
• C. I will exercise every day to improve my strength and endurance.
• D. I will drink plenty of fluids to help thin my mucus.

Correct answer: C

Rationale: The correct answer is C. While exercise is important for clients with COPD, daily exercise may be too strenuous. Clients should be encouraged to exercise regularly but should be advised to avoid overexertion. Statements A, B, and D demonstrate appropriate understanding and management of COPD symptoms.

3. A client is 12 hours postoperative and has a chest tube to a disposable water-seal drainage system with suction. The healthcare provider should intervene for which of the following observations?

• A. Constant bubbling in the suction-control chamber
• B. Continuous bubbling in the water-seal chamber
• C. Bloody drainage in the collection chamber
• D. Fluid-level fluctuations in the water-seal chamber

Correct answer: B

Rationale: Continuous bubbling in the water-seal chamber indicates an air leak, which can compromise the system's integrity and affect the client's respiratory status. The other options are expected findings in a client with a chest tube drainage system: constant bubbling in the suction-control chamber indicates proper suction function, bloody drainage in the collection chamber is expected in the immediate postoperative period, and fluid-level fluctuations in the water-seal chamber demonstrate normal drainage and lung re-expansion.

4. A client with a new tracheostomy is being seen in the oncology clinic. What finding by the nurse best indicates that goals for the nursing diagnosis Impaired Self-Esteem are being met?

• A. The client demonstrates a good understanding of stoma care.
• B. The client has joined a book club that meets at the library.
• C. Family members take turns assisting with stoma care.
• D. Skin around the stoma is intact without signs of infection.

Correct answer: B

Rationale: The client joining a book club that meets outside the home and requires him or her to go out in public is the best indicator that goals for Impaired Self-Esteem are being met. This social activity indicates an improvement in self-confidence and willingness to engage with others, which are essential aspects of self-esteem. The other choices, while positive, do not directly address self-esteem concerns related to social interaction and confidence.

5. A nursing student is providing tracheostomy care. What action by the student requires intervention by the instructor?

• A. Holding the device securely when changing ties
• B. Suctioning the client first if secretions are present
• C. Tying a square knot at the back of the neck
• D. Using half-strength peroxide for cleansing

Correct answer: C

Rationale: When providing tracheostomy care, it is important to ensure the client's safety and prevent pressure ulcers. When securing ties that require knotting, the knot should be placed at the side of the client's neck, not at the back. Tying a square knot at the back of the neck could lead to discomfort, pressure ulcers, or accidental tightening. Holding the device securely, suctioning the client as needed, and using appropriate cleansing solutions are all essential components of tracheostomy care.
