A nurse is collecting data from a client who has macular degeneration. Which of the following findings should the nurse expect?
Nystagmus
Astigmatism
Loss of central vision
Client reports sharp pain
The Correct Answer is C
Rationale:
A. Nystagmus: Nystagmus is characterized by involuntary eye movements and is typically associated with vestibular disorders, multiple sclerosis, or congenital conditions. It is not a symptom of macular degeneration, which primarily affects the retina.
B. Astigmatism: Astigmatism is a refractive error due to an irregularly shaped cornea or lens. It is unrelated to macular degeneration, which involves degeneration of the macula—the part of the retina responsible for sharp central vision.
C. Loss of central vision: Macular degeneration leads to progressive deterioration of the macula, resulting in blurred or complete loss of central vision while peripheral vision remains intact. This is a hallmark symptom and significantly affects activities like reading and recognizing faces.
D. Client reports sharp pain: Macular degeneration does not typically cause pain. It is a painless condition, and the presence of sharp eye pain may suggest another acute ocular issue such as glaucoma or injury, not related to macular changes.

Correct Answer is A
Explanation
Rationale:
A. Maintain the client in high-Fowler's position: Placing the client in high-Fowler's position improves lung expansion and decreases pulmonary congestion by lowering venous return to the heart. This is a priority intervention for managing dyspnea and crackles in heart failure.
B. Increase the client's intake of oral fluids: Increasing fluid intake may worsen fluid overload in clients with heart failure. These clients typically require fluid restrictions to prevent exacerbation of symptoms like pulmonary edema.
C. Instruct the client to cough every 4 hr: While coughing can help clear secretions, the symptoms in this scenario are related to fluid overload, not mucus accumulation. Coughing alone will not relieve the pulmonary congestion seen in heart failure.
D. Encourage the client to ambulate to loosen secretions: Ambulation has benefits but is not the first action when the client is short of breath and showing signs of pulmonary congestion. Activity should be limited until respiratory status stabilizes.
Correct Answer is C
Explanation
Rationale:
A. Removing an NG tube: Removing a nasogastric tube is a task that can be safely delegated to a licensed practical nurse (LPN) under appropriate supervision, as it is considered a stable, routine procedure that does not require complex assessment.
B. Administering a subcutaneous insulin injection: LPNs are trained and authorized to administer subcutaneous injections, including insulin, as long as the client's condition is stable and the dose is clearly prescribed.
C. Providing discharge teaching about home IV medication therapy: Discharge education involving IV therapy requires comprehensive teaching, clinical judgment, and evaluation of understanding, which falls within the scope of practice of a registered nurse (RN).
D. Collecting a sputum culture: Collecting a sputum specimen is a basic nursing task that can be performed by an LPN or even by trained assistive personnel, depending on facility policy. It does not require the expertise of an RN.
