An inborn error of metabolism that causes a premature destruction of RBC?
- A. G6PD
- B. Homocystinuria
- C. Phenylketonuria
- D. Celiac Disease
Correct Answer: A
Rationale: Glucose-6-phosphate dehydrogenase (G6PD) deficiency is an inborn error of metabolism that leads to the premature destruction of red blood cells (hemolysis). G6PD is an enzyme responsible for protecting red blood cells from oxidative damage. In individuals with G6PD deficiency, the red blood cells are more susceptible to oxidative stress, leading to their destruction and resulting in hemolytic anemia. This condition is commonly triggered by certain medications, infections, or dietary factors that cause oxidative stress, leading to hemolysis. Homocystinuria, Phenylketonuria, and Celiac Disease are metabolic disorders that do not typically result in the premature destruction of red blood cells.

What is the primary nursing intervention to prevent bacterial endocarditis?
- A. Institute measures to prevent dental procedures.
- B. Counsel parents of high-risk children about prophylactic antibiotics.
- C. Observe children for complications, such as embolism and heart failure.
- D. Encourage restricted mobility in susceptible children.
Correct Answer: B
Rationale: The primary nursing intervention to prevent bacterial endocarditis is to counsel parents of high-risk children about prophylactic antibiotics. This is recommended by the American Heart Association for children with certain heart conditions before dental procedures that could introduce bacteria into the bloodstream. By providing education on the importance of prophylactic antibiotics, nurses can help prevent bacterial endocarditis by reducing the risk of bacterial infection associated with dental procedures in susceptible children. It is important to involve the parents in the decision-making process and ensure they understand the rationale behind the use of prophylactic antibiotics to protect their child's heart health.
A patient is having difficulty swallowing following a stroke, and a swallowing evaluation is ordered. The ff. nursing interventions might be recommended to help prevent aspiration during eating except:
- A. Provide clear liquids only until the patient can swallow solid foods.
- B. Have the patient swallow twice after each bite
- C. Place food on the unaffected side of the patient's mouth
- D. Check if the patient's mouth for pocketing of food
Correct Answer: A
Rationale: Providing clear liquids only until the patient can swallow solid foods is not recommended as it restricts the patient's diet unnecessarily. In the case of difficulty swallowing after a stroke, it is important to modify the food consistency and provide appropriate techniques to support safe swallowing. Limiting the patient to clear liquids only could lead to inadequate nutrition and hydration. Instead, it is important to modify the diet consistency and use strategies such as altering the food presentation, having the patient swallow twice after each bite, placing food on the unaffected side of the mouth, and checking for pocketing of food to help prevent aspiration.
During examination of a toddler's extremities, the nurse notes that the child is bowlegged. What should the nurse recognize regarding this finding?
- A. Abnormal and requires further investigation
- B. Abnormal unless it occurs in conjunction with knock-knee
- C. Normal if the condition is unilateral or asymmetric
- D. Normal because the lower back and leg muscles are not yet well developed
Correct Answer: A
Rationale: Bowlegged appearance in a toddler is not considered normal and should prompt further investigation by a healthcare provider. Bowlegs, also known as genu varum, can be caused by various underlying conditions such as vitamin D deficiency, rickets, or genetic factors. It is important to determine the cause of bowleggedness in order to provide appropriate treatment or interventions to promote proper development of the child's legs. Bowleggedness on its own is not considered a normal variation in toddler development and warrants further assessment.
The lowest fasting plasma glucose level suggestive of a diagnosis of diabetes is:
- A. 90mg/dl
- B. 126mg/dl
- C. 115mg/dl
- D. 180mg/dl
Correct Answer: B
Rationale: A fasting plasma glucose level of 126mg/dl or higher is considered to be indicative of diabetes mellitus. This value represents the threshold for diagnosing diabetes based on fasting glucose levels according to the American Diabetes Association (ADA) criteria. Fasting glucose levels between 100-125mg/dl indicate impaired fasting glucose, which is a precursor to diabetes. Therefore, a fasting plasma glucose level of 126mg/dl is the lowest level at which a diagnosis of diabetes can be suggested.
