Nursing Elites

1. A home health nurse visits a client who has COPD and receives oxygen at 2 L/min via nasal cannula. The client reports difficulty breathing. Which of the following actions is the nurse's priority?

• A. Increase the oxygen flow to 3 L/min.
• B. Assess the client's respiratory status.
• C. Call emergency services for the client.
• D. Have the client cough and expectorate secretions.

Correct answer: B

Rationale: When a client with COPD on oxygen therapy reports difficulty breathing, the priority action for the nurse is to assess the client's respiratory status. This involves evaluating the client's oxygen saturation levels, respiratory rate, effort of breathing, lung sounds, and overall respiratory distress. By assessing the client's respiratory status, the nurse can determine the severity of the situation and make appropriate decisions regarding further interventions, such as adjusting oxygen flow rate, providing respiratory treatments, or seeking emergency assistance if necessary.

2. A client reports a headache and vertigo after turning on his furnace for the first time this season. The nurse should suspect which of the following conditions?

• A. Carbon monoxide poisoning
• B. Heat stroke
• C. Hypersensitivity reaction
• D. Oxygen toxicity

Correct answer: A

Rationale: When a client reports headache and vertigo after turning on the furnace for the first time, it suggests carbon monoxide poisoning. Carbon monoxide is an odorless, colorless gas that can be released by malfunctioning heating systems. Symptoms of carbon monoxide poisoning include headache, dizziness, weakness, nausea, and confusion. It is crucial for the nurse to suspect this condition promptly to ensure the client's safety and well-being.

3. A nurse cares for a female client who has a family history of cystic fibrosis. The client asks, Will my children have cystic fibrosis? How should the nurse respond?

• A. Since many of your family members are carriers, your children will also be carriers of the gene.
• B. Cystic fibrosis is an autosomal recessive disorder. If you are a carrier, your children will have the disorder.
• C. Since you have a family history of cystic fibrosis, I would encourage you & your partner to be tested.
• D. Cystic fibrosis is caused by a protein that controls the movement of chloride. Adjusting your diet will decrease the spread of this disorder.

Correct answer: C

Rationale: Cystic fibrosis is an autosomal recessive disorder in which both gene alleles must be mutated for the disorder to be expressed. The nurse should encourage both the client & partner to be tested for the abnormal gene. The other statements are not true.

4. 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.

5. Which action should the nurse take to reduce the risk of ventilator-associated pneumonia in a client with an endotracheal tube receiving mechanical ventilation?

• A. Position the head of the client's bed flat
• B. Turn the client every 4 hours
• C. Brush the client's teeth with a suction toothbrush every 12 hours
• D. Provide humidity by maintaining moisture within the ventilator tubing

Correct answer: C

Rationale: Ventilator-associated pneumonia (VAP) is a common complication in clients receiving mechanical ventilation. Oral hygiene is crucial in reducing the risk of VAP. Brushing the client's teeth with a suction toothbrush every 12 hours helps prevent bacterial colonization in the oral cavity, which can be aspirated into the lungs. Positioning the head of the bed flat can increase the risk of aspiration. Turning the client every 4 hours is important for preventing pressure ulcers but not directly related to reducing VAP. Providing humidity in the ventilator tubing helps maintain airway moisture but does not directly address the risk of VAP.
