Elderly persons with pernicious anemia should be instructed:
- A. to increase their dietary intake of foods high in B12.
- B. that they do not need to return for follow-up for at least a month after initiation of treatment.
- C. that oral B12 is safer and less expensive than parenteral replacement.
- D. that diarrhea can be a transient side effect of B12 injections.
Correct Answer: D
Rationale: Elderly persons with pernicious anemia, a condition characterized by vitamin B12 deficiency due to lack of intrinsic factor, should be informed about the potential side effects of B12 injections. Diarrhea is a known transient side effect of B12 injections, along with pain and burning at the injection site, and peripheral vascular thrombosis. Increasing dietary intake of B12-rich foods would not be sufficient due to the malabsorption issue in pernicious anemia. Follow-up is essential in managing pernicious anemia, so instructing patients they do not need to return for follow-up is incorrect. While oral B12 may be a suitable option for some cases, it is not the preferred choice for pernicious anemia where malabsorption is the primary issue.

What is an appropriate intervention for the client with suspected genitourinary trauma and visible blood at the urethral meatus?
- A. Insertion of a Foley catheter.
- B. Performing an in-and-out catheter specimen for urinalysis.
- C. Obtaining a voided urine specimen for urinalysis.
- D. Ordering a urinalysis by the physician.
Correct Answer: D
Rationale: When a client presents with suspected genitourinary trauma and visible blood at the urethral meatus, obtaining a voided urine specimen for urinalysis is an appropriate intervention. This helps assess for any urinary tract injuries or abnormalities without further traumatizing the area. Insertion of a Foley catheter (Choice A) should be avoided as it can worsen the existing trauma. Performing an in-and-out catheter specimen (Choice B) involves unnecessary manipulation and can increase the risk of complications. Ordering a urinalysis by the physician (Choice D) may delay the assessment compared to obtaining a direct voided urine specimen.
A month after receiving a blood transfusion, an immunocompromised client develops fever, liver abnormalities, a rash, and diarrhea. The nurse should suspect this client has:
- A. no relation to the blood transfusion.
- B. graft-versus-host disease (GVHD).
- C. myelosuppression.
- D. an allergic reaction to a recent medication.
Correct Answer: B
Rationale: In this scenario, the symptoms of fever, liver abnormalities, rash, and diarrhea in an immunocompromised client a month after a blood transfusion are indicative of graft-versus-host disease (GVHD). GVHD occurs when white blood cells in donor blood attack the tissues of an immunocompromised recipient. This process can manifest within a month of the transfusion. While choices 1 and 4 are plausible, it is crucial for the nurse to consider the possibility of GVHD in immunocompromised transfusion recipients due to the significant risk. Myelosuppression, choice C, typically presents with decreased blood cell counts and is not consistent with the symptoms described. An allergic reaction to medication, choice D, would present with different manifestations such as itching, hives, or anaphylaxis, which are not described in the scenario.
Erythropoietin used to treat anemia in clients with renal failure should be given in conjunction with:
- A. iron, folic acid, and B12.
- B. an increase in protein in the diet.
- C. vitamins A and C.
- D. an increase in calcium in the diet.
Correct Answer: A
Rationale: Erythropoietin is necessary for red blood cell (RBC) production, and in clients with renal failure who lack endogenous erythropoietin, exogenous erythropoietin is administered. However, for erythropoietin to effectively stimulate RBC production, adequate levels of iron, folic acid, and vitamin B12 are crucial. These nutrients are essential for RBC synthesis and maturation. Therefore, the correct answer is to give iron, folic acid, and B12 with erythropoietin. Choice B, an increase in protein in the diet, is not necessary for RBC production and may exacerbate uremia in clients with renal failure. Choices C and D, vitamins A and C, and an increase in calcium in the diet, respectively, are not directly related to RBC production and are not required to enhance the effectiveness of erythropoietin.
Which of the following blood pressure parameters indicates PIH? Elevation over a baseline of:
- A. 30 mmHg systolic and/or 15 mmHg diastolic.
- B. 40 mmHg systolic and/or 20 mmHg diastolic.
- C. 10 mmHg systolic and/or 5 mmHg diastolic.
- D. 20 mmHg systolic and/or 20 mmHg diastolic.
Correct Answer: A
Rationale: The correct answer is A: 30 mmHg systolic and/or 15 mmHg diastolic. These parameters indicate mild PIH (pregnancy-induced hypertension). Mild preeclampsia is characterized by an increase in systolic blood pressure greater than 30 mmHg or an increase in diastolic blood pressure greater than 15 mmHg, observed on two readings taken 6 hours apart (or reaching 140/90). Choice B (40 mmHg systolic and/or 20 mmHg diastolic) represents a more significant elevation and would indicate a more severe condition than mild PIH. Choices C (10 mmHg systolic and/or 5 mmHg diastolic) and D (20 mmHg systolic and/or 20 mmHg diastolic) do not meet the criteria for indicating PIH as they are below the accepted parameters for mild PIH.
The anemias most often associated with pregnancy are:
- A. folic acid and iron deficiency.
- B. folic acid deficiency and thalassemia.
- C. iron deficiency and thalassemia.
- D. thalassemia and B12 deficiency.
Correct Answer: B
Rationale: Folic acid and iron deficiency anemia are the most common types of anemia associated with pregnancy. Approximately 50% of pregnant women experience this type of anemia. Iron deficiency anemia during pregnancy typically results from the increased plasma volume, rather than a decrease in iron levels. Moreover, if a woman has iron deficiency anemia before pregnancy, it often worsens during pregnancy. Folic acid deficiency is also prevalent during pregnancy due to the increased demand for this nutrient to support fetal development. Thalassemia and B12 deficiency, while types of anemia, are not as commonly associated with pregnancy compared to folic acid and iron deficiency anemia, making them incorrect choices in this context.
