Correct Answer: A

Rationale: The correct answer is A: Type I hypersensitivity reaction. This type of reaction involves the release of histamine from mast cells and basophils, leading to symptoms like hives. It is characterized by the involvement of IgE antibodies. In this case, the patient developed hives quickly after exposure to the allergen, indicating an immediate hypersensitivity reaction typical of Type I.

Choices B, C, and D are incorrect because they are associated with different mechanisms and timeframes of hypersensitivity reactions. Type II involves antibody-mediated cell destruction, Type III involves immune complex deposition, and Type IV is a delayed-type hypersensitivity reaction mediated by T cells, none of which are consistent with the rapid onset of hives seen in this patient.

Correct Answer: A

Rationale: The correct answer is A because referenced daily intakes (RDIs) provide values for protein, vitamins, and minerals essential for maintaining health. RDIs do not focus solely on fat, cholesterol, and fiber percentages (
B). RDIs are different from recommended daily allowances (RDAs) but do not replace them (
C). RDIs are not specifically used to develop diets for chronic illnesses requiring a specific calorie intake (
D).

Correct Answer: B

Rationale: The correct answer is B: Implement an automatic sign-off. This guideline helps reduce data entry errors by ensuring that all entries are completed and saved before exiting the system, thus maintaining confidentiality. Bypassing the firewall (
A) would compromise data security. Creating a password with just letters (
C) may not be secure enough. Using a programmed speed-dial key when faxing (
D) is unrelated to reducing data entry errors or maintaining confidentiality.

Correct Answer: B

Rationale:
Step 1: Prostate surgery can damage nerves responsible for erectile function.

Step 2: Nerve damage can lead to erectile dysfunction post-prostatectomy.

Step 3:
Choice B correctly states that all prostatectomies carry a risk of nerve damage and consequent erectile dysfunction, aligning with the potential impact of surgery on sexual function.

Step 4: Other choices lack accuracy: A incorrectly attributes erectile dysfunction solely to hormonal changes, C falsely suggests temporary nature of dysfunction, and D wrongly claims no risk of dysfunction due to modern techniques.

Correct Answer: B

Rationale: The correct answer is B: Jejunostomy tube. This tube is chosen because the patient has a history of aspiration pneumonia, which puts them at risk for aspiration if feeds are administered into the stomach. By administering feeds through a jejunostomy tube, the risk of aspiration pneumonia is minimized as the feed bypasses the stomach. Nasogastric tube (
A) and Nasointestinal tube (
C) would still deliver feeds to the stomach, increasing the risk of aspiration. PEG tube (
D) is also not ideal as it delivers feeds directly to the stomach, which is not recommended for patients at risk for aspiration.
