A. Dress the infant warmly to prevent undue chilling

B. Cut the infant's fingernails and toenails regularly

C. Use bubble bath instead of soap for bathing

D. Wash the infant's clothes with mild detergent and fabric softener

Expert Explanatory Rationale

Correct Answer: Cut the infant's fingernails and toenails regularly

Question 2 of 10

A client has a rate-responsive permanent pacemaker in his upper chest. The nurse understands rate-responsive to mean which of the following?

A. A pacemaker function prevents excessive changes in the pacing rate.

B. The pacing rate increases above the normal pacing rate with sudden bradycardia.

C. The pacemaker switches from atrial tracking mode to nontracking mode with atrial fibrillation.

D. The pacing rate increases when the sensors note increased activity.

Expert Explanatory Rationale

Correct Answer: The pacing rate increases when the sensors note increased activity.

A rate-responsive pacemaker increases the pacing rate when sensors detect increased activity (D), mimicking normal heart rate response. Other options (A, B, C) describe different pacemaker functions.

Question 3 of 10

Prior to drawing blood for blood gas analysis, the nurse conducts the modified Allen test to ensure there is adequate collateral circulation. The nurse asks the client to extend the wrist over a rolled towel and make a fist. Place the following steps (Roman numerals) in order from first to last.

B. Palpate the ulnar and radial pulses and apply pressure to both arteries.

C. Observe the hand for color.

D. Release the ulnar artery while maintaining pressure on the radial artery.
