Question 1 of 5
Elderly persons with pernicious anemia should be instructed:
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.
Question 2 of 5
Which of the following blood pressure parameters indicates PIH? Elevation over a baseline of:
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.
Question 3 of 5
A healthcare professional is assessing a patient's right lower extremity. The extremity is warm to touch, red, and swollen. The patient is also running a low fever. Which of the following conditions would be the most likely cause of the patient's condition?
Correct Answer: D
Rationale: The patient's presentation of a warm, red, swollen extremity with a low fever is indicative of cellulitis, which is inflammation of cellular tissue. Cellulitis is commonly associated with these symptoms due to a bacterial infection in the skin and underlying tissues. Herpes (
Choice
A) is a viral infection that typically presents with grouped vesicles, not the warm, red, swollen presentation seen in cellulitis. Scleroderma (
Choice
B) is a chronic autoimmune condition affecting the skin and connective tissue, presenting differently from the acute symptoms of cellulitis. Dermatitis (
Choice
C) refers to skin inflammation, which does not typically present with the described symptoms of warmth, redness, swelling, and low fever observed in cellulitis.
Question 4 of 5
Chemotherapeutic agents often produce a degree of myelosuppression including leukopenia. Leukopenia does not present immediately but is delayed several days or weeks because:
Correct Answer: D
Rationale: Leukopenia does not present immediately after chemotherapy because time is required to clear circulating cells before the effect on precursor cell maturation in the bone marrow becomes evident. Leukopenia is characterized by an abnormally low white blood cell count. The correct answer is D because the white cell count is not immediately affected by chemotherapy.
Choices A, B, and C are incorrect as they pertain to red blood cells (hemoglobin and hematocrit), which are not directly related to the delayed onset of leukopenia.
Question 5 of 5
A pregnant Asian client who is experiencing morning sickness wants to take ginger to relieve the nausea. Which of the following responses by the nurse is appropriate?
Correct Answer: A
Rationale: The correct response is to offer to consult with the physician regarding the use of ginger, showing cultural sensitivity. Ginger is known to help relieve nausea, especially in pregnancy.
Choice A is the correct answer as it respects the client's preference for a home remedy and involves the physician in the decision-making process.
Choice B dismisses the client's preference for a home remedy without exploring its potential benefits.
Choice C makes a generalized statement discrediting the effectiveness of herbs, which is not evidence-based and disregards the client's beliefs.
Choice D offers an alternative without addressing the client's specific request, failing to acknowledge the client's autonomy and cultural background.
