Which of the following is TRUE about the auscultation of blood pressure?

Correct Answer: B

Rationale: The stethoscope bell auscultates low-frequency Korotkoff sounds e.g., tapping in BP unlike the diaphragm (high-frequency). Pulse +4 (bounding), +1 (weak), and sound pitch (low) differ. Nurses use this e.g., bell placement for clear readings, per auscultation technique.

Correct Answer: B

Rationale: The Dark Period (16th-18th centuries) began with Luther's 1517 Reformation e.g., closing church hospitals challenging Catholicism. Unlike Apprentice (religious care), Contemporary (modern), or Educative (training), this era saw nursing decline as secular forces took over, a low point before its professional resurgence.

Correct Answer: B

Rationale: A patient's chart is secondary compiled by others (e.g., past notes), not directly from the patient (primary). Tertiary (textbooks) or mixed don't fit. Charts offer history e.g., prior vitals crucial for continuity, per nursing documentation standards.

Correct Answer: A

Rationale: Younger people have higher pulses e.g., 80-100 bpm vs. 60-80 adults due to metabolism. Males post-puberty lower (strength), digitalis slows (negative chronotropic), lying reduces (rest). Nurses note this e.g., pediatric norms per physiology.

Correct Answer: B

Rationale: Parallax error misaligns eye level with meniscus e.g., higher eyes read lower (false low), lower read higher. Eye-level accuracy is key. Nurses position e.g., meniscus height for true BP, per precision.
