Correct Answer: B

Rationale: The correct answer is B: Affective. The caregiver's decision to postpone toilet training indicates a change in feelings or attitudes, which falls under the affective domain of learning. The affective domain relates to emotions, values, and attitudes. In this scenario, the caregiver's willingness to delay toilet training due to new information reflects a shift in attitude impacted by the educational session provided by the nurse. Choices A, C, and D are incorrect. The cognitive (choice A) domain involves intellectual skills and knowledge, the psychomotor (choice C) domain involves physical skills, and kinesthetic (choice D) is often used interchangeably with the psychomotor domain, which focuses on physical movement and coordination.

Correct Answer: C

Rationale: The correct answer is C. Colorectal cancer screening for individuals at average risk typically begins at age 50. One of the recommended options for routine screening is a fecal occult blood test done annually. Choice A is incorrect as blood samples are not used for routine colorectal cancer screening. Choice B is incorrect because colonoscopies usually start at age 50, not 60. Choice D is incorrect as sigmoidoscopies are recommended every 5 years, not every 10 years, for individuals at average risk for colon cancer.

Correct Answer: A

Rationale: When auscultating the chest, normal breathing sounds are expected in a healthy individual. Wheezing is a high-pitched whistling sound that indicates narrowed airways and is often heard in conditions like asthma. Crackles are fine, crackling sounds heard on inspiration or expiration and are associated with conditions like pneumonia or heart failure. Stridor is a high-pitched, harsh sound heard during inspiration due to upper airway obstruction. Therefore, choices B, C, and D indicate abnormal respiratory findings, while choice A signifies normal breathing sounds.

Correct Answer: B

Rationale: In this scenario, a client who has undergone thoracic surgery and is being admitted from the PACU requires a high level of nursing care. Registered nurses (RNs) have the education and training necessary to provide the complex care and monitoring needed for a post-thoracic surgery client. Charge nurses may oversee units but may not always be directly involved in providing bedside care. Practical nurses (PNs) have a different scope of practice compared to RNs and may not have the advanced skills needed for post-thoracic surgery care. Assistive personnel (AP) provide valuable support but do not have the qualifications to manage the care of a client following thoracic surgery.

Correct Answer: B

Rationale: The correct technique for IV catheter insertion involves inserting the needle at a 10 to 30-degree angle with the bevel up. This angle facilitates proper vein puncture, reduces the risk of complications, and minimizes trauma to the vein. Choice A is incorrect because threading the needle into the vein at an angle of 10 to 30 degrees with the bevel up is the correct technique, not threading it all the way into the vein. Choice C is incorrect because applying pressure 1.2 inches below the insertion site before removing the needle is not a standard step in IV catheter insertion. Choice D is incorrect because selecting the antecubital fossa vein solely based on its size and accessibility may not be the most appropriate criterion; vein selection should also consider factors like vein condition and patient comfort.
