Question 1 of 5
A staff nurse is teaching a client who has Addison's disease about the disease process. The client asks the nurse what causes Addison's disease. Which of the following responses should the nurse make?
Correct Answer: A
Rationale:
Correct Answer: A
Rationale:
1. Addison's disease is characterized by adrenal insufficiency.
2. Aldosterone is a hormone produced by the adrenal gland that helps regulate blood pressure and electrolyte balance.
3. Lack of aldosterone production in Addison's disease leads to electrolyte imbalances and low blood pressure.
4.
Therefore, the correct answer is A as the lack of aldosterone production by the adrenal gland is the primary cause of Addison's disease.
Summary of other choices:
B. Addison's disease is not caused by a viral infection, so this choice is incorrect.
C. Addison's disease is not caused by the overproduction of cortisol, as it is associated with cortisol deficiency.
D. The most common cause of Addison's disease is an autoimmune disorder where the body attacks the adrenal glands, leading to their dysfunction.
Question 2 of 5
A home health nurse assesses an older adult with vision loss due to glaucoma. What is a safety hazard?
Correct Answer: B
Rationale: The correct answer is B: Presence of scatter rugs in the kitchen. Scatter rugs pose a tripping hazard for individuals with vision loss, especially in areas like the kitchen where spills and slippery surfaces are common. The other choices are incorrect because: A - Bright overhead lighting can actually be beneficial for those with vision loss by improving visibility; C - Using contrasting colors can aid in distinguishing objects and pathways; D - Wearing slip-resistant shoes can help prevent falls.
Question 3 of 5
A nurse is caring for a client who has pericarditis and reports feeling a new onset of palpitations and shortness of breath. Which of the following assessments should indicate to the nurse that the client may have developed atrial fibrillation?
Correct Answer: A
Rationale: The correct answer is A: Different apical and radial pulses. In atrial fibrillation, the atria quiver instead of contracting effectively, leading to irregular heartbeat and pulse. This results in a discrepancy between the apical (heard by auscultation) and radial (felt at the wrist) pulses. Shortness of breath on exertion (
B), excessive sweating (
C), and systolic blood pressure of 150 mm Hg (
D) are not specific to atrial fibrillation and can occur in various conditions.
Question 4 of 5
A nurse is admitting a client who has a serum calcium level of 12.3 mg/dL and initiates cardiac monitoring. Which of the following findings should the nurse expect during the initial assessment?
Correct Answer: A
Rationale: The correct answer is A: Lethargy. A serum calcium level of 12.3 mg/dL indicates hypercalcemia. In hypercalcemia, calcium affects the central nervous system, leading to lethargy, weakness, and confusion. Lethargy is a common early symptom of hypercalcemia. Hypertension is not typically associated with hypercalcemia. Muscle spasms are more common in hypocalcemia. Severe agitation is not a typical manifestation of hypercalcemia.
Question 5 of 5
A nurse in an emergency department is caring for a client who reports substernal chest pain and dyspnea. The client is vomiting and is diaphoretic. Which of the following laboratory tests are used to diagnose a myocardial infarction? (Select all that apply.)
Correct Answer: A
Rationale: The correct answer is A. Troponin I, Troponin T, CPK, and Myoglobin are all specific laboratory tests used to diagnose a myocardial infarction. Troponin I and T are cardiac biomarkers released into the bloodstream following myocardial cell injury. Creatine phosphokinase (CPK) is an enzyme found in high concentrations in the heart muscle, and elevated levels indicate myocardial damage. Myoglobin is a protein released from damaged muscle cells, including cardiac muscle. These tests provide crucial information to confirm the diagnosis of a myocardial infarction.
Plasma low-density lipoproteins are not specific for diagnosing a myocardial infarction. White blood cell count is not typically used for diagnosing a myocardial infarction, although it may be elevated in response to inflammation associated with heart damage. Blood glucose level is not specific for diagnosing a myocardial infarction and
