Which of the following provides that nurses must be a member of a national nurse organization?

Correct Answer: B

Rationale: The 1981 Philippine Nursing Code of Ethics mandates national organization membership (PNA) e.g., ensuring accountability. R.A. 877 (old law), R.A. 7164 (1991 law), and PNA memos differ. This reflects nursing's collective duty, reinforcing unity and ethical standards in practice.

Correct Answer: A

Rationale: Oral temp is most accessible e.g., quick tongue placement needing minimal prep, unlike rectal (invasive), tympanic (equipment), or axillary (longer). Convenient for alert patients, nurses favor it e.g., clinics for routine ease, per practice standards.

Correct Answer: D

Rationale: Axillary temp is safest, least invasive no mucosal entry e.g., armpit avoids rectal (perforation), oral (biting), or tympanic (ear) risks. Ideal for infants, nurses use it e.g., frail patients for safety, per non-invasive guidelines.

Correct Answer: A

Rationale: Diastolic pressure is when ventricles rest e.g., 80 in 120/80 showing resistance. Systole (contraction), preload (filling), pulse pressure (difference) differ. Nurses measure this e.g., hypertension for health, per BP definitions.

Correct Answer: C

Rationale: HCT 70% e.g., polycythemia can raise BP (viscosity) or lower (poor flow), unlike hypervolemia (raises BP, GFR), or epinephrine (raises). Nurses assess this e.g., anemia for impacts, per dynamics.
