Question 1 of 5
The kidneys regulate acid-base balance by all of the following mechanisms except:
Correct Answer: B
Rationale: The kidneys help regulate acid-base balance through several mechanisms, including excreting hydrogen ions (H+), reabsorbing or excreting bicarbonate (HCO3-) into the blood, and retaining or excreting hydrogen ions. However, the kidneys do not play a direct role in reabsorbing carbon dioxide into the blood. Carbon dioxide is mainly managed in the body through the respiratory system, where it is exhaled as a waste product of metabolism.
Question 2 of 5
A client has had heavy menstrual bleeding for 6 months. Her gynecologist diagnoses microcytic hypochromic anemia and prescribes ferrous sulfate (Feosol), 300mg PO daily. Before initiating iron therapy, the nurse reviews the client's medical history. Which condition would contraindicate the use of ferrous sulfate?
Correct Answer: D
Rationale: Severely impaired liver function is a contraindication for the use of ferrous sulfate. In patients with liver disease, iron metabolism can be affected, leading to potential toxicity from iron accumulation. Ferrous sulfate is primarily metabolized by the liver, so in cases of severely impaired liver function, the metabolism of the drug may be altered, leading to potential adverse effects. It is important to consider alternative iron therapy options in patients with severe liver impairment to avoid potential complications.
Question 3 of 5
The LEAST important advice for a 2-month-old baby with excessive crying is
Correct Answer: C
Rationale: Changing formula is less critical if the baby is gaining weight adequately.
Question 4 of 5
All the following are Test results seen in JRA EXCEPT :
Correct Answer: D
Rationale: Juvenile idiopathic arthritis (JIA), previously known as Juvenile Rheumatoid Arthritis (JRA), is a chronic inflammatory disorder that primarily affects children. In JIA, common test results include an increase in ESR (Erythrocyte Sedimentation Rate), positive RF (Rheumatoid Factor), and positive IgM & IgG antibodies. However, a positive CA 9 result is not typically associated with JRA. CA 9 (Carbonic Anhydrase 9) is not a commonly used marker for diagnosing or monitoring JIA, so it would not be expected to be seen in test results for this condition.
Question 5 of 5
If a patient has elevated pulmonary vascular pressures, the nurse understands that the patient is most likely to develop which of the ff. physiological cardiac changes?
Correct Answer: D
Rationale: Elevated pulmonary vascular pressures can lead to pulmonary hypertension, which causes increased pressure in the right side of the heart. The right ventricle has to work harder to pump blood against the increased resistance in the pulmonary circulation. Over time, this can result in the development of right ventricular hypertrophy as the muscle of the right ventricle thickens in response to the increased workload. This is a compensatory mechanism to try to maintain cardiac output despite the increased pressure in the pulmonary circulation. Left atrial atrophy, left ventricular hypertrophy, and right atrial atrophy are not typically associated with elevated pulmonary vascular pressures.
