1. Why is a precise amount of oxygen necessary for a patient with COPD to prevent which complication?
- A. Cardiac arrest related to increased partial pressure of carbon dioxide in arterial blood (PaCO2)
- B. Circulatory overload due to hypervolemia
- C. Respiratory excitement
- D. Inhibition of the respiratory hypoxic stimulus
Correct answer: D
Rationale: In patients with COPD, the respiratory drive is often stimulated by low oxygen levels. Administering too much oxygen can inhibit this hypoxic drive, leading to respiratory depression and potential respiratory failure. Therefore, it is crucial to carefully regulate the oxygen therapy to prevent the inhibition of the respiratory hypoxic stimulus in COPD patients.
2. Which instrument is used for auscultation?
- A. Percussion hammer
- B. Audiometer
- C. Stethoscope
- D. Sphygmomanometer
Correct answer: C
Rationale: Auscultation involves listening to internal sounds in the body, such as heart and lung sounds. The instrument used for auscultation is a stethoscope, which allows healthcare providers to listen to these sounds. The percussion hammer is used to elicit sounds on the body, the audiometer is used to measure hearing ability, and the sphygmomanometer is used to measure blood pressure. Therefore, the correct answer is 'Stethoscope.'
3. What is the transparent membrane that focuses the light entering the eyes onto the retina?
- A. Lens
- B. Sclera
- C. Cornea
- D. Pupils
Correct answer: A
Rationale: The correct answer is the lens. The lens is a transparent structure in the eye that helps to focus light onto the retina, which is essential for clear vision. The cornea and sclera are also important parts of the eye, but the lens specifically plays a crucial role in focusing light onto the retina. The sclera is the white outer layer of the eye that helps maintain the shape of the eye, while the cornea is the clear outer covering of the eye that helps to refract light into the eye.
4. A client is being instructed on how to perform pursed-lip breathing. Which of the following should be included in the plan of care?
- A. Take quick breaths upon inhalation.
- B. Place your hand over your stomach.
- C. Take a deep breath in through your nose.
- D. Puff your cheeks upon exhalation.
Correct answer: C: Take a deep breath in through your nose.
Rationale: Pursed-lip breathing is a breathing technique that involves inhaling slowly through the nose and exhaling gently through pursed lips. This technique helps improve breathing efficiency and can be beneficial for individuals with respiratory conditions. Instructing the client to take a deep breath in through the nose is essential for proper execution of pursed-lip breathing, making choice C the correct answer.
5. A client is being assessed by a nurse who is 30 minutes postoperative following an arterial thrombectomy. Which of the following findings should the nurse report?
- A. Chest pain
- B. Muscle spasms
- C. Cool, moist skin
- D. Incisional pain
Correct answer: Chest pain
Rationale: Chest pain is a critical finding postoperatively, especially after an arterial thrombectomy, as it could indicate complications like myocardial infarction or pulmonary embolism. It requires immediate attention and further evaluation. Muscle spasms, cool moist skin, and incisional pain are important to assess but not as urgent as chest pain in this scenario.
