Nursing Elites

1. What assessment findings should lead the nurse to suspect Down syndrome in a newborn?

• A. Hypertonia and dark skin
• B. Low-set ears and a simian crease
• C. Inner epicanthal folds and a high, domed forehead
• D. Long, thin fingers and excessive hair

Correct answer: B

Rationale: The correct answer is B: 'Low-set ears and a simian crease.' These are key physical characteristics commonly seen in newborns with Down syndrome. Low-set ears, along with a simian crease (a single palmar crease), are indicative of Down syndrome. Choices A, C, and D are incorrect because hypertonia, dark skin, inner epicanthal folds, a high, domed forehead, long, thin fingers, and excessive hair are not specific features associated with Down syndrome in newborns. Therefore, the presence of low-set ears and a simian crease should raise suspicion for Down syndrome and prompt further evaluation.

2. The nurse is caring for a client with acute pancreatitis. Which laboratory result is most indicative of this condition?

• A. Elevated serum amylase
• B. Decreased serum bilirubin
• C. Increased blood urea nitrogen (BUN)
• D. Decreased alkaline phosphatase

Correct answer: A

Rationale: Elevated serum amylase is the most indicative laboratory result of acute pancreatitis. In this condition, the pancreas becomes inflamed, leading to the leakage of amylase and lipase into the bloodstream. Elevated serum amylase levels are a classic finding in acute pancreatitis. Choices B, C, and D are not typically associated with acute pancreatitis. Decreased serum bilirubin, increased blood urea nitrogen (BUN), and decreased alkaline phosphatase levels are not specific markers for acute pancreatitis.

3. The parents of a child who has had a myringotomy are instructed by the nurse to place the child in which position?

• A. Supine
• B. On the affected side
• C. On the unaffected side
• D. In Trendelenburg's position

Correct answer: B

Rationale: Placing the child on the affected side after a myringotomy facilitates ear drainage. This position helps prevent accumulation of fluids in the ear canal, aiding in the healing process. Placing the child in the supine position (Choice A) or on the unaffected side (Choice C) may not be as effective in promoting drainage. The Trendelenburg's position (Choice D) with the head lower than the body is used for conditions requiring increased venous return, not for post-myringotomy care.

4. How are type IV hypersensitivity reactions different from all other types (I, II, or III) of hypersensitivity reactions?

• A. They involve antigen-antibody complexes.
• B. They are mediated by T cells and do not involve antibodies.
• C. They result in immediate allergic reactions.
• D. They are the least severe form of hypersensitivity.

Correct answer: B

Rationale: Type IV hypersensitivity reactions are mediated by T cells and cytokine release, leading to delayed reactions, unlike types I, II, and III, which involve antibodies. Choice A is incorrect because type IV reactions do not involve antigen-antibody complexes. Choice C is incorrect as type IV reactions do not result in immediate allergic reactions. Choice D is incorrect as type IV reactions are not the least severe form of hypersensitivity; in fact, they are known to cause significant tissue damage and inflammation.

5. In the change of shift report, the nurse is told that a client has a stage 2 pressure ulcer. Which ulcer appearance is most likely to be observed?

• A. Shallow open ulcer with a red-pink wound bed.
• B. Intact skin with non-blanchable redness.
• C. Full-thickness tissue loss with visible fat.
• D. Full-thickness tissue loss with exposed bone, tendon, or muscle.

Correct answer: A

Rationale: The correct answer is A: 'Shallow open ulcer with a red-pink wound bed.' Stage 2 pressure ulcers involve partial-thickness skin loss and typically appear as shallow open ulcers with a red-pink wound bed. Choice B describes a stage 1 ulcer, where the skin is intact but shows non-blanchable redness. Choice C describes a stage 3 ulcer, with full-thickness tissue loss exposing fat. Choice D is characteristic of a stage 4 ulcer, where there is full-thickness tissue loss exposing bone, tendon, or muscle. Therefore, option A best fits the description of a stage 2 pressure ulcer.
