Correct Answer: B

Rationale: Placing the client's arm in a dependent position is the correct action when inserting a peripheral IV catheter for an older adult client. This position helps veins dilate due to gravity, facilitating easier insertion of the IV catheter. Choice A is incorrect because catheters are typically inserted at a lower angle, around 10-30 degrees. Choice C is unnecessary unless excessive hair impedes the insertion process. Choice D is incorrect as veins in the hand are generally smaller and more prone to complications, making them less ideal for IV therapy in older adults.

Correct Answer: D

Rationale: The correct answer is 'Upper arm circumference.' Upper arm circumference is a better indicator of total muscle mass in adolescents compared to height, weight, or triceps skinfold thickness. Triceps skinfold thickness primarily reflects subcutaneous fat, while weight and height are not specific to muscle mass. Upper arm circumference directly measures the muscle mass in the upper arm and can provide a more accurate assessment in this context. Therefore, choices A, B, and C are incorrect because they do not directly reflect total muscle mass in adolescents.

Correct Answer: C

Rationale: When assessing bowel sounds, it is crucial to listen before performing any palpation as palpation can alter bowel sounds. The correct technique involves placing the diaphragm of the stethoscope over each quadrant of the abdomen to listen for bowel sounds. Auscultating for at least 5 minutes is recommended to accurately determine the presence or absence of bowel sounds. Asking the client to cough is not necessary for assessing bowel sounds and may not provide relevant information. Therefore, option C is the correct choice as it follows the appropriate procedure for assessing bowel sounds.

Correct Answer: A

Rationale: To ensure accurate testing, a minimum amount of stool is required for specimen collection, typically at least 2 inches of formed stool. This amount provides an adequate sample for testing. Wearing sterile gloves is important for infection control but is not specifically required for stool specimen collection. Using a culturette is not typically necessary for collecting stool specimens. Recording the date and time the stool was collected is essential to ensure timely processing but does not directly impact the collection of the specimen itself.

Correct Answer: A

Rationale: The correct first action for the nurse to take when a client removes the covering from an ice pack is to observe the appearance of the skin under the ice pack. This assessment is crucial to check for any skin damage or adverse reactions resulting from direct contact with the ice pack. Instructing the client about the importance of the covering (Choice B) can follow the skin assessment. Reapplying the covering (Choice C) before skin assessment may potentially cause harm. Asking the client about the duration of ice application (Choice D) is not the immediate priority; ensuring skin integrity is the primary concern.
