A client is diagnosed with megaloblastic anemia caused by vitamin B12 deficiency. The physician begins the client on cyanocobalamin (Betalin-12), 100mcg IM daily. Which substance influences Vitamin B12 absorption?

  • A. Intrinsic factor
  • B. Histamine
  • C. Hydrochloric acid
  • D. Liver enzyme
Correct Answer: A

Rationale: Intrinsic factor is a glycoprotein produced by the parietal cells of the stomach. It is essential for the absorption of vitamin B12 in the intestine. Vitamin B12 binds to intrinsic factor in the stomach, forming a complex that is absorbed in the ileum of the small intestine. Without intrinsic factor, vitamin B12 absorption is significantly impaired, leading to conditions like pernicious anemia, which is a type of megaloblastic anemia caused by vitamin B12 deficiency. By administering cyanocobalamin (Betalin-12) intramuscularly, the need for intrinsic factor in the absorption process is bypassed, which is necessary in cases where intrinsic factor production or function is disrupted.

A man‘s blood type is AB and he requires a blood transfusion. To prevent complications of blood incompatibilities, which blood type may the client receive?

  • A. Type A or B blood only
  • B. Type O blood only
  • C. Type AB blood only
  • D. Either type A, B, AB, or O blood
Correct Answer: C

Rationale: As the man's blood type is AB, he can only receive blood from donors with type AB blood. This is because individuals with type AB blood are universal recipients, meaning they can safely receive blood from any blood type without risking complications. Blood types A, B, and O all contain antigens that could cause a reaction if transfused into someone with type AB blood. Therefore, to prevent any complications of blood incompatibility, the client in this case should only receive blood with type AB.

Which of the ff diets does the nurse recommend for clients with hypertension under the physicians guidance?

  • A. The Food Guide Pyramid
  • B. The South Beach Diet

These dietary components are known to help lower blood pressure and improve overall health.

It is important for clients to follow the DASH diet under the guidance of a physician to ensure it is tailored to their individual needs and health status.

  • B. Destruction of brain cells has occurred, interrupting mental activity
  • C. Teaching based on information progressing from the simple to the complex
  • D. A minimum of information should be given, since he is unaware of surrounding
Correct Answer: A

Rationale: Providing new information slowly and in small amounts to a confused individual, like Mr. Reyes, is important because confusion or delirium can be a defense mechanism against further stress. By giving information gradually, it allows the individual to better absorb and process the information without becoming overwhelmed, which can further exacerbate their confusion. This approach also helps reduce the risk of causing additional stress or agitation in the individual, thus promoting a more conducive environment for cognitive processing and understanding.
