1. What drives respiration in a patient with advanced chronic respiratory failure?

• A. Hypoxemia
• B. Hypocapnia
• C. Hypercapnia
• D. None of the above

Correct answer: A

Rationale: In patients with advanced chronic respiratory failure, such as those with chronic obstructive pulmonary disease (COPD), the respiratory drive shifts from being primarily stimulated by high levels of carbon dioxide (hypercapnia) to being driven by low oxygen levels (hypoxemia). This shift is due to the body's adaptation to chronic respiratory acidosis and hypoxemia. As a result, hypoxemia becomes the primary stimulus for respiration in these patients. Hypocapnia, a low level of carbon dioxide, is not a common driver of respiration in patients with advanced chronic respiratory failure. Therefore, the correct answer is hypoxemia.

2. A patient with pneumonia has a fever of 101.4 F (38.6 C), a nonproductive cough, and an oxygen saturation of 88%. The patient complains of weakness, fatigue, and needs assistance to get out of bed. Which nursing diagnosis should the nurse assign as the highest priority?

• A. Hyperthermia related to infectious illness
• B. Impaired transfer ability related to weakness
• C. Ineffective airway clearance related to thick secretions
• D. Impaired gas exchange related to respiratory congestion

Correct answer: D

Rationale: The correct answer is 'Impaired gas exchange related to respiratory congestion.' While all the nursing diagnoses are relevant to the patient's condition, the priority should be given to impaired gas exchange due to the patient's low oxygen saturation level of 88%. This indicates a significant risk of hypoxia for all body tissues unless the gas exchange is improved. Addressing impaired gas exchange is crucial to ensure adequate oxygenation and prevent further complications. Hyperthermia, impaired transfer ability, and ineffective airway clearance are important concerns but addressing gas exchange takes precedence in this scenario.

3. A patient who has a history of chronic obstructive pulmonary disease (COPD) was hospitalized for increasing shortness of breath and chronic hypoxemia (SaO2 levels of 89% to 90%). In planning for discharge, which action by the nurse will be most effective in improving compliance with discharge teaching?

• A. Start giving the patient discharge teaching on the day of discharge
• B. Have the patient repeat the instructions immediately after teaching
• C. Accomplish the patient teaching just before the scheduled discharge
• D. Arrange for the patient's caregiver to be present during the teaching

Correct answer: D

Rationale: Hypoxemia interferes with the patient's ability to learn and retain information, so having the patient's caregiver present will increase the likelihood that discharge instructions will be followed. Having the patient repeat the instructions will indicate that the information is understood at the time, but it does not guarantee retention of the information. Giving discharge instructions just before discharge is not ideal as the patient is likely to be distracted and anxious at that time. Teaching the patient about discharge on the day of admission is not recommended because the patient may be more hypoxemic and anxious than usual, making it difficult for them to absorb and retain the information effectively. Therefore, arranging for the patient's caregiver to be present during the teaching session is the best option to ensure proper compliance and understanding of the discharge instructions.

4. What would be the most appropriate follow-up by the home care nurse for a 57-year-old male client with a hemoglobin of 10 g/dl and a hematocrit of 32%?

• A. Ask the client if he has noticed any bleeding or dark stools
• B. Tell the client to call 911 and go to the emergency department immediately
• C. Schedule a repeat Hemoglobin and Hematocrit in 1 month
• D. Tell the client to schedule an appointment with a hematologist

Correct answer: A

Rationale: The correct answer is to ask the client if he has noticed any bleeding or dark stools. Normal hemoglobin for males is 13.0 - 18 g/dl, and normal hematocrit for males is 42 - 52%. The values of hemoglobin and hematocrit provided for the client are below normal, indicating mild anemia. The first step for the nurse is to inquire about any signs of bleeding or changes in stools that could suggest bleeding from the gastrointestinal tract. This helps in assessing the possible cause of the low hemoglobin and hematocrit levels. The other options are not appropriate as calling 911 and going to the emergency department immediately is not warranted for mild anemia, scheduling a repeat test in 1 month delays addressing the current concern, and referring the client to a hematologist may be premature without investigating the cause of the low levels first.

5. A patient has taken an overdose of aspirin. Which of the following should a nurse closely monitor during acute management of this patient?

• A. Onset of pulmonary edema
• B. Metabolic alkalosis
• C. Respiratory alkalosis
• D. Parkinson's disease type symptoms

Correct answer: A

Rationale: The correct answer is to monitor the onset of pulmonary edema. In cases of aspirin overdose, metabolic acidosis is a common consequence that can lead to the development of pulmonary edema. Early signs of aspirin poisoning include symptoms like tinnitus, hyperventilation, vomiting, dehydration, and fever. Late signs may manifest as drowsiness, bizarre behavior, unsteady walking, and coma. Aspirin poisoning can cause abnormal breathing that is typically rapid and deep. Pulmonary edema may occur due to increased capillary permeability in the lungs, leading to the leakage of proteins and fluid transudation in renal and pulmonary tissues. Changes in renal tubule permeability can also affect colloid osmotic pressure, potentially contributing to pulmonary edema. Monitoring pulmonary edema is crucial in managing aspirin overdose cases to prevent further complications. Choices B, C, and D are incorrect because metabolic alkalosis, respiratory alkalosis, and Parkinson's disease type symptoms are not typically associated with aspirin overdose and are not primary concerns in its acute management.
