The nurse chose a cheaper, effective med for Mr. Gary. This is an example of?

Correct Answer: A

Rationale: Choosing cheaper, effective med is cost-effectiveness (A) maximizing value, per definition. Utilization (B) resources, literacy (C) understanding, transition (D) moves not cost-specific. A fits the nurse's economical choice for Mr. Gary, making it correct.

Correct Answer: C

Rationale: A sore throat on chlorpromazine (Thorazine) may signal agranulocytosis, a rare, life-threatening drop in white cells, requiring immediate physician report urgent in schizophrenia care. Thirst, weight gain, or napping are common but less acute. Nurses flag this, prompting blood counts, ensuring rapid intervention to prevent infection.

Correct Answer: B

Rationale: Pulling the lower lid down and instilling drops in the conjunctival sac ensures accurate delivery to a 4-year-old's eye, minimizing trauma prone positioning, high dropper, or dry wiping risks injury or inefficacy. Nurses use this, calming the child, ensuring medication (e.g., antibiotic) reaches the target safely.

Correct Answer: D

Rationale: Fever's onset (chill phase) features vasoconstriction e.g., pale, cold skin as the setpoint rises. Hot/flushed (flush phase), thirst (later), or convulsions (hyperpyrexia) follow. Nurses expect this e.g., shivering in Marianne, guiding warming measures, per physiology.

Correct Answer: B

Rationale: Coronary arteries fill during diastole e.g., heart relaxes, aortic pressure pushes blood in. Systole (contraction), valve timing differ. Nurses note this e.g., angina for perfusion, per cardiac cycle.

Correct Answer: A

Rationale: Drying and wrapping the newborn prevents hypothermia, a priority post-delivery oxygen, vital signs, and vitamin K follow stabilization. Nurses act swiftly, ensuring thermoregulation, supporting transition to extrauterine life in the critical first minutes.

Correct Answer: B

Rationale: The orthopneic position maximizes chest expansion, easing breathing in dyspnea.

Correct Answer: C

Rationale: Dorothea Orem's self-care theory posits that nurses assist clients in performing self-care activities to maintain or improve health, emphasizing individual responsibility and nursing support when deficits arise. Developed in the mid-20th century, this theory frames nursing as a facilitative process, helping clients meet universal needs like air, water, and food, or recover from illness through tailored interventions. Florence Nightingale focused on environmental modifications to aid healing, not self-care. Virginia Henderson's Need Theory defines nursing as assisting with basic needs until independence is regained, differing from Orem's self-care focus. Sister Callista Roy's Adaptation Model centers on adjusting to stimuli, not self-care per se. Orem's framework remains influential, guiding nurses to empower clients in managing their health, particularly in chronic or rehabilitative contexts, by fostering independence and collaboration.

Correct Answer: C

Rationale: Benedict's test boiling urine with solution, color change e.g., detects glucose simply, unlike acetic (protein), nitrazine (pH), litmus (acid/base). Nurses use e.g., rural for resourcefulness, per diagnostics.
