A client is suspected to have a pituitary tumor due to signs of diabetes insipidus. What initial test does the nurse help to prepare the client for?

Radioimmunoassay

Magnetic resonance imaging (MRI)

Radioactive iodine uptake test

Nuclear scan

Answer and Explanation

The Correct Answer is B

Reasoning:

Choice A reason: Radioimmunoassay measures hormone levels, such as ADH, but is not the initial test for a suspected pituitary tumor. It may confirm hormonal deficiencies but cannot visualize structural abnormalities like tumors, which are better assessed by imaging techniques like MRI, making it a secondary diagnostic tool in this context.

Choice B reason: Magnetic resonance imaging (MRI) is the initial test for a suspected pituitary tumor. It provides detailed images of the pituitary gland, identifying structural abnormalities like tumors that may cause diabetes insipidus by disrupting ADH production. MRI is non-invasive and highly sensitive for detecting pituitary lesions, guiding further management.

Choice C reason: Radioactive iodine uptake tests assess thyroid function, not pituitary tumors. These tests are used for thyroid disorders like hyperthyroidism, which are unrelated to diabetes insipidus or pituitary pathology. They do not visualize the pituitary gland or confirm structural causes of ADH deficiency.

Choice D reason: A nuclear scan, such as a bone or thyroid scan, is not used to diagnose pituitary tumors. It assesses other conditions, like bone metastases or thyroid activity, but lacks specificity for pituitary imaging. MRI is the preferred modality for visualizing pituitary abnormalities causing diabetes insipidus.

Correct Answer is D

Explanation

Reasoning:

Choice A reason: Continuous oxygen therapy is not a standard preventive measure for sickle cell crises. Oxygen is used during acute crises to treat hypoxia from vaso-occlusion, but daily hydration is more effective for prevention, as it reduces blood viscosity and sickling, making this inappropriate.

Choice B reason: Avoiding all sports is overly restrictive for sickle cell anemia. Moderate exercise can be safe with proper hydration and rest. Complete avoidance does not directly prevent crises and may reduce quality of life, whereas hydration directly addresses the risk of sickling and vaso-occlusion.

Choice C reason: Avoiding activities causing shortness of breath is partially correct, as overexertion can trigger hypoxia and crises. However, it is less specific than hydration, which directly reduces blood viscosity and sickling, preventing crises more effectively across various situations, not just during exertion.

Choice D reason: Drinking at least 8 glasses of water daily is critical in sickle cell anemia to prevent crises. Adequate hydration reduces blood viscosity, preventing red blood cell sickling and vaso-occlusion. Dehydration increases sickling risk, making consistent fluid intake a key preventive strategy for this client.

A. Weakness B. Fatigue C. Glucose intolerance D. Abdominal pain

Correct Answer is D

Explanation

Reasoning:

Choice A reason: Weakness is a general symptom in sickle cell disease due to chronic anemia and reduced oxygen delivery but is not specific to liver complications. Weakness results from systemic hypoxia or energy depletion, not localized hepatic vaso-occlusion or damage, making it less indicative.

Choice B reason: Fatigue is common in sickle cell disease due to chronic hemolysis and anemia but does not specifically indicate liver complications. It reflects reduced red blood cell oxygen-carrying capacity, not hepatic involvement, which requires more localized signs like pain to confirm organ-specific issues.

Choice C reason: Glucose intolerance is not a typical liver complication in sickle cell disease. While chronic disease may affect metabolism, liver complications in SCD involve vaso-occlusion or iron overload, not direct glucose regulation issues, making this finding less relevant to hepatic involvement in this context.

Choice D reason: Abdominal pain, particularly in the right upper quadrant, indicates a liver complication in sickle cell disease. Vaso-occlusion in hepatic vessels or iron overload from transfusions can cause hepatic ischemia or hepatomegaly, leading to pain, a specific sign of liver involvement in SCD exacerbations.
