A nurse is caring for a client who the provider suspects might have pernicious anemia. The nurse should expect the provider to prescribe which of the following diagnostic tests?
Schilling test
Haptoglobin
Sweat test
Antinuclear antibodies
The Correct Answer is A
A. Schilling test: This is the correct answer. The Schilling test is used to diagnose pernicious anemia, which is caused by vitamin B12 deficiency. The test measures the absorption of vitamin B12 in the gastrointestinal tract.
B. Haptoglobin: Haptoglobin is a test used to assess hemolysis and is not specific for pernicious anemia.
C. Sweat test: The sweat test is used to diagnose cystic fibrosis and is not relevant to the diagnosis of pernicious anemia.
D. Antinuclear antibodies: Antinuclear antibodies are tested to diagnose autoimmune disorders, such as systemic lupus erythematosus (SLE), and are not specific to pernicious anemia.

Correct Answer is D
Explanation
A. Nausea: While respiratory distress can lead to various symptoms, nausea is not a typical manifestation of hypoxemia during an asthma attack.
B. Dysphagia: Difficulty swallowing (dysphagia) is not a direct manifestation of hypoxemia during an asthma attack. Asthma primarily affects the airways and respiratory function.
C. Hypotension: Hypotension (low blood pressure) is not typically associated with hypoxemia during an asthma attack. In fact, increased respiratory effort and stress can lead to increased heart rate and, in some cases, increased blood pressure.
D. Agitation: This is the correct answer. Hypoxemia, which occurs when there is an inadequate amount of oxygen in the blood, can lead to increased restlessness, anxiety, and agitation. Agitation is a common manifestation of the body's response to insufficient oxygenation.
Correct Answer is C
Explanation
A. Impaired tissue perfusion: While impaired tissue perfusion is a concern in clients with varicose veins, the presence of ulcerations indicates that skin integrity is already compromised. Addressing impaired skin integrity is a more immediate concern.
B. Alteration in activity tolerance: Alteration in activity tolerance may be a consequence of impaired tissue perfusion and impaired skin integrity, but the priority is to address the current skin breakdown and prevent further complications.
C. Impaired skin integrity: This is the correct answer. The presence of varicose veins, ulcerations, and lower extremity edema indicates compromised skin integrity. The nurse should prioritize interventions to promote wound healing, prevent infection, and address the underlying causes contributing to impaired skin integrity.
D. Alteration in body image: While body image concerns may arise in clients with varicose veins, the immediate priority is addressing the physical complications such as impaired skin integrity to prevent further deterioration.
