Nursing Elites

1. Which statement correctly explains the etiology of Down syndrome?

• A. There is an extra chromosome on the 21st pair.
• B. There is a missing chromosome on the 21st pair.
• C. There are two pairs of the 21st chromosome.
• D. The 21st chromosome pair is missing.

Correct answer: A

Rationale: The correct answer is A: 'There is an extra chromosome on the 21st pair.' Down syndrome is caused by the presence of an extra copy of chromosome 21, known as trisomy 21. This additional genetic material leads to the characteristics associated with Down syndrome. Choices B, C, and D are incorrect because Down syndrome is not due to a missing chromosome or having two pairs of the 21st chromosome; it results from the presence of an extra chromosome on the 21st pair.

2. The nurse is teaching a client how to collect a sputum specimen. Which steps should the nurse instruct the client to follow when collecting sputum?

• A. Breathe deeply, followed by swallowing.
• B. Breathe deeply, followed by spitting into a cup.
• C. Breathe deeply, followed by coughing up the sputum.
• D. Breathe deeply, followed by clearing the throat.

Correct answer: C

Rationale: The correct answer is to instruct the client to breathe deeply followed by coughing up the sputum. This method ensures that the specimen is collected from the lower respiratory tract and is not contaminated by saliva. Choice A (swallowing) does not result in sputum collection, while choice B (spitting into a cup) may lead to saliva contamination. Choice D (clearing the throat) is not an effective way to collect sputum as it may involve getting rid of saliva, not sputum.

3. The nurse caring for a hospitalized older client with a left hip fracture as a result of a fall at home notices different assessment findings. Which assessment finding warrants immediate intervention by the nurse?

• A. Pain rated 7/10 on the pain scale.
• B. Mild swelling at the fracture site.
• C. Small amount of bleeding from the surgical site.
• D. Left extremity capillary refill greater than 5 seconds.

Correct answer: D

Rationale: The correct answer is D. A left extremity capillary refill greater than 5 seconds indicates poor blood flow to the extremity, which is a sign of compromised circulation. This finding requires immediate intervention by the nurse to prevent complications such as tissue damage or necrosis. Choices A, B, and C are important assessments but do not indicate an immediate need for intervention like the delayed capillary refill in choice D.

4. What is a priority action for the nurse when caring for a client with suspected meningitis?

• A. Isolate the client in a private room
• B. Administer intravenous antibiotics
• C. Obtain a throat culture
• D. Perform a chest x-ray

Correct answer: B

Rationale: Administering intravenous antibiotics is the priority when caring for a client with suspected meningitis. The prompt administration of antibiotics is crucial to treat bacterial meningitis and prevent potential complications. Isolating the client in a private room may be necessary to prevent the spread of infection, but antibiotic administration takes precedence. Obtaining a throat culture and performing a chest x-ray are important diagnostic measures, but they do not address the immediate need for antibiotic therapy in suspected bacterial meningitis.

5. Which laboratory results should the nurse anticipate to be abnormal in a child with hemophilia?

• A. Prothrombin time
• B. Bleeding time
• C. Platelet count
• D. Partial thromboplastin time

Correct answer: D

Rationale: In a child with hemophilia, the nurse should anticipate an abnormality in the partial thromboplastin time (PTT) due to the deficiency in clotting factors. Prothrombin time, bleeding time, and platelet count are typically normal in hemophilia. Prothrombin time measures the extrinsic pathway of coagulation and is not affected in hemophilia. Bleeding time assesses platelet function, which is normal in hemophilia as the issue lies with clotting proteins, not platelets. Platelet count is also expected to be normal unless there is another underlying condition affecting platelet production or function.
