Prenatally, malaria parasites hide at the
- A. Bone marrow
- B. Placental bed
- C. Fetal circulation
- D. Uterine muscle
Correct Answer: B
Rationale: The correct answer is B: Placental bed. Malaria parasites hide in the placental bed during pregnancy to avoid detection by the immune system. This location provides a safe haven for the parasites to survive and replicate without being cleared by the mother's immune response. The placental bed offers a rich blood supply and a favorable environment for the parasites to thrive.
Incorrect choices:
A: Bone marrow - Malaria parasites do not typically hide in the bone marrow during pregnancy.
C: Fetal circulation - Malaria parasites do not hide in the fetal circulation; they primarily reside in the placental bed.
D: Uterine muscle - Malaria parasites do not hide in the uterine muscle; the placental bed is the main site of sequestration during pregnancy.

Haematinics, dietary advice, and close surveillance are management plans for
- A. Moderate anaemia
- B. Mild anaemia
- C. Severe anaemia
- D. Anaemia prevention
Correct Answer: A
Rationale: The correct answer is A: Moderate anaemia. Haematinics, dietary advice, and close surveillance are appropriate management plans for moderate anaemia to improve iron levels and overall health. For mild anaemia, dietary changes alone may be sufficient. Severe anaemia often requires more aggressive treatments like blood transfusions. Anaemia prevention focuses on strategies to avoid developing anaemia rather than managing an existing case.
Mrs. Jenner is a 41-year-old female who is being evaluated for persistent nausea. She had an abdominal CT scan that reported three hepatic hemangiomas ranging from 3 to 5 cm. The AGACNP knows that the appropriate response to this report is to
- A. Arrange for large-bore needle biopsy
- B. Order hepatic ultrasound annually to follow progression
- C. Consult surgery for resection
- D. Document the finding in the patient’s chart
Correct Answer: B
Rationale: The correct answer is B. Ordering hepatic ultrasound annually to follow progression is the appropriate response for hepatic hemangiomas. Biopsy is not recommended due to the risk of bleeding. Surgery is usually not required unless there are complications. Documenting the finding is important but does not address the need for monitoring. Ultrasound allows for non-invasive monitoring of the hemangiomas over time to assess for growth or complications, guiding further management if needed.
A characteristic of monozygotic twins includes
- A. Always of the same sex
- B. Share a similar fingerprint pattern
- C. Have different blood groups
- D. Superfetation is a common finding
Correct Answer: A
Rationale: The correct answer is A: Always of the same sex. Monozygotic twins develop from a single fertilized egg, so they have the same genetic material, making them always the same sex. This is due to the fact that the sex of an individual is determined by the chromosomes inherited from the parents. This is a fundamental principle of genetics. Choices B, C, and D are incorrect because monozygotic twins can have different fingerprints, blood groups, and superfetation (conception that occurs during an existing pregnancy) is not common in monozygotic twins.
Which of the following is not a true statement with respect to decision making for a cognitively impaired patient?
- A. Only a court can declare a patient incompetent
- B. Impaired cognition does not make a person incompetent
- C. Living wills typically are honored if a person is terminally ill
- D. A patient can give informed consent if not declared incompetent
Correct Answer: C
Rationale: The correct answer is C because living wills typically are not always honored for cognitively impaired patients. Step-by-step rationale: A) Incorrect - A court can declare a patient incompetent if they are unable to make decisions. B) Incorrect - Impaired cognition can indeed make a person incompetent. D) Incorrect - A patient must have the capacity to understand information and make decisions to give informed consent.
Positive fasting blood sugar and oral glucose tolerance test, as well as being symptomatic, is diagnostic of
- A. Potential diabetes mellitus
- B. Gestational diabetes mellitus
- C. Clinical diabetes mellitus
- D. Chemical diabetes mellitus
Correct Answer: B
Rationale: The correct answer is B, Gestational diabetes mellitus. This condition is diagnosed when a pregnant woman exhibits symptoms of diabetes and has elevated fasting blood sugar and abnormal oral glucose tolerance test results. This specific combination of symptoms and test results during pregnancy points towards gestational diabetes mellitus.
A: Potential diabetes mellitus - Incorrect. The symptoms combined with abnormal test results suggest an active condition, not potential.
C: Clinical diabetes mellitus - Incorrect. While the symptoms and test results indicate diabetes, the context of pregnancy suggests gestational diabetes.
D: Chemical diabetes mellitus - Incorrect. This term is not commonly used in medical practice and does not specifically address the condition in the given scenario.
