Pneumocystic pneumonia. Which anemias are described as microcytic, hypochromic anemia?
- A. Vitamin B12 and iron deficiency anemia
- B. Folic acid and iron deficiency anemia
- C. Iron deficiency anemia and thalassemia
- D. Sickle cell anemia and anemia if chronic disease
Correct Answer: C
Rationale: Microcytic, hypochromic anemia is characterized by small red blood cells with decreased hemoglobin content. Iron deficiency anemia and thalassemia are the two main types of anemia that present with these characteristics. Iron deficiency anemia is caused by a lack of iron in the body, which is essential for the production of hemoglobin. Thalassemia is a genetic disorder that results in decreased production of normal hemoglobin. Both conditions lead to small, pale red blood cells, fitting the description of microcytic, hypochromic anemia. Other choices such as Vitamin B12 deficiency anemia (choice A), folic acid deficiency anemia (choice B), sickle cell anemia (choice D), and anemia of chronic disease (choice D) typically present as normocytic or macrocytic anemias.

Which of the ff points should a nurse include in the teaching plan for clients who have potential for hypovolemia?
- A. Avoid alcohol and caffeine
- B. Increase intake of milk and dairy products
- C. Increase intake of dried peas and beans
- D. Avoid table salt or food containing sodium
Correct Answer: A
Rationale: Clients at risk for hypovolemia, which is a condition characterized by low blood volume, should be advised to avoid alcohol and caffeine. Alcohol and caffeine are known to have diuretic effects, which can further deplete the body's fluid volume and worsen the condition. By avoiding alcohol and caffeine, clients can help maintain adequate fluid levels in the body and reduce the risk of exacerbating hypovolemia. Additionally, it is important for clients at risk for hypovolemia to stay hydrated by consuming adequate amounts of water or other hydrating fluids.
When performing a physical examination on an infant, the nurse in charge notes abnormally low- set ears. This finding is associated with:
- A. Otogenous tetanus
- B. Tracheoesophageal fistula
- C. Congenital heart defects
- D. Renal anomalies
Correct Answer: C
Rationale: Abnormally low-set ears are often associated with certain congenital anomalies, including congenital heart defects. When a nurse notes this finding during a physical examination of an infant, it is important to consider the possibility of congenital anomalies and further assessment for associated conditions. Low-set ears alone are not diagnostic of a specific congenital heart defect, but they can serve as a clue to support the need for further evaluation to rule out any underlying cardiac issues. Other congenital anomalies that may be associated with low-set ears include renal anomalies, which makes option D a distractor in this case.
