1. A client with chronic obstructive pulmonary disease (COPD) presented with shortness of breath. Oxygen therapy was started at 2 liters/minute via nasal cannula. The arterial blood gases (ABGs) after treatment were pH 7.36, PaO2 52, PaCO2 59, HCO3 33. Which statement describes the most likely cause of the simultaneous increase in both PaO2 and PaCO2?
- A. The client is hyperventilating due to anxiety.
- B. The hypoxic drive was reduced by the oxygen therapy.
- C. The client is experiencing respiratory alkalosis.
- D. The client is experiencing metabolic acidosis.
Correct answer: B
Rationale: Oxygen therapy can reduce the hypoxic drive in COPD patients, leading to increased PaCO2 levels while improving oxygenation (PaO2). In this case, the increase in PaO2 and PaCO2 is due to the reduction of the hypoxic drive by the supplemental oxygen. Choice A is incorrect because hyperventilation would lead to decreased PaCO2. Choice C is incorrect as the ABG values do not indicate respiratory alkalosis. Choice D is incorrect as the ABG values do not support metabolic acidosis.
2. The nurse is teaching a client with newly diagnosed type 1 diabetes about insulin administration. Which statement by the client indicates a need for further teaching?
- A. I will rotate my injection sites to avoid lipodystrophy.
- B. I will check my blood sugar before meals and at bedtime.
- C. I will use the same needle for 3 days if I keep it clean.
- D. I will keep my insulin refrigerated until I need it.
Correct answer: C
Rationale: The correct answer is C because insulin needles should be disposed of after a single use to prevent infection. Reusing the same needle for three days can lead to infection and is not a safe practice. Choices A, B, and D demonstrate good understanding of insulin administration and diabetes management, so they do not indicate a need for further teaching.
3. A community health nurse is conducting a home visit to assess a family's health needs. What is the first step in this process?
- A. Develop a care plan
- B. Conduct a physical examination
- C. Establish rapport with the family
- D. Provide health education
Correct answer: C
Rationale: Establishing rapport with the family is crucial in the initial stages of a home visit. It helps build trust, open communication channels, and allows the nurse to gain insight into the family's health needs and concerns. Developing a care plan (Choice A) comes after the assessment phase, where information is gathered. Conducting a physical examination (Choice B) is a part of the assessment but typically follows establishing rapport. Providing health education (Choice D) is important but usually occurs after the assessment and care planning stages.
4. The nurse discontinues a continuous IV heparin infusion for a male client on strict bedrest and is now preparing to administer the client's first dose of enoxaparin. Prior to giving this subcutaneous injection, which assessment finding requires additional intervention by the nurse?
- A. Current lab report indicates an Aptt at 1.5 times the client's control
- B. The client states that his right calf is aching and wants pain medication
- C. The spouse is assisting the client who is shaving with an electric razor
- D. Several bruised areas are noted on the client's upper extremities bilaterally
Correct answer: D
Rationale: The correct answer is D. Bruised areas on the client's upper extremities bilaterally indicate an increased risk of bleeding, which requires careful assessment before administering enoxaparin. Bruising suggests potential issues with clotting and hemostasis, making it crucial for the nurse to further evaluate the client's bleeding risk. Choices A, B, and C do not directly relate to the assessment of bleeding risk associated with enoxaparin administration and are therefore incorrect. Choice A provides information about the client's Aptt, which is not directly relevant to assessing bleeding risk for enoxaparin. Choice B addresses pain management, and Choice C involves the client's daily activities with no direct link to the bleeding risk assessment.
5. What information should be included in the preoperative plan of care for an infant with myelomeningocele?
- A. Positioning the infant supine with a pillow under the buttocks
- B. Covering the sac with saline-soaked nonadhesive gauze
- C. Wrapping the infant snugly in a blanket
- D. Applying a diaper to prevent fecal soiling of the sac
Correct answer: B
Rationale: Covering the sac with saline-soaked nonadhesive gauze is essential in the preoperative care of an infant with myelomeningocele. This practice helps prevent infection and maintains moisture around the sac before surgery, promoting optimal healing outcomes. Positioning the infant supine with a pillow under the buttocks may be uncomfortable and unnecessary. Wrapping the infant snugly in a blanket does not address the specific care needs of the myelomeningocele. Applying a diaper over the sac can increase the risk of infection and should be avoided in this case.
