Extract:
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: D
Rationale: This is the correct explanation of the cause of Addison's disease, which involves adrenal insufficiency.
Question 2 of 5
A nurse is caring for a client who has hypernatremia and requires IV fluid therapy due to his NPO status. Which of the following solutions should the nurse prepare to infuse for this client?
Correct Answer: A
Rationale: 0.45% sodium chloride, also known as half-normal saline, is a hypotonic solution with a lower concentration of sodium than normal serum levels. It can help to lower the sodium levels in a client with hypernatremia by diluting the excess sodium in the body.
Question 3 of 5
Maria, an elementary student, was rushed to the hospital due to vomiting and a decreased level of consciousness. The patient displays slow and deep (Kussmaul breathing), and he is lethargic and irritable in response to stimulation. He appears to be dehydrated-his eyes are sunken and mucous membranes are dry-and he has a two-week history of polydipsia, polyuria, and weight loss. Measurement of arterial blood gas shows pH 7.0, PaO2 90 mm Hg, PaCO2 23 mm Hg, and HCO3 12 mmol/L; other results are Na+ 126 mmol/L, K+ 5 mmol/L, and Cl-95 mmol/L. What is your assessment?
Correct Answer: B
Rationale: Metabolic acidosis is indicated by a low pH and a decreased bicarbonate (HCO3) level. The body attempts to compensate by hyperventilating, evidenced by Kussmaul breathing, to decrease PaCO2. This compensation is partial because the pH is still significantly lower than normal.
Question 4 of 5
A nurse in a public clinic is researching health data on culturally diverse populations in the community. Which of the following population groups should the nurse anticipate having end-stage renal disease due to diabetes mellitus?
Correct Answer: A
Rationale: Black Americans have a higher prevalence of diabetes mellitus compared to other racial/ethnic groups in the United States, and diabetes is a leading cause of end-stage renal disease.
Question 5 of 5
A nurse is caring for a client who has metabolic alkalosis. Which of the following actions should the nurse take?
Correct Answer: C
Rationale: Metabolic alkalosis can lead to cardiac dysrhythmias due to electrolyte imbalances, particularly hypokalemia. Continuous cardiac monitoring is essential to promptly identify and manage any dysrhythmias that may occur.
