The patient's blood pressure is 140/60. Which value will the nurse record for the pulse pressure?
- A. 60
- B. 80
- C. 140
- D. 200
Correct Answer: B
Rationale: Pulse pressure is systolic minus diastolic: 140 - 60 = 80 (B). 60 (A) is diastolic. 140 (C) is systolic. 200 (D) is unrelated. Choice B is correct, reflecting arterial pressure dynamics, a key nursing calculation.

A patient is experiencing pyrexia. Which piece of equipment will the nurse obtain to monitor this condition?
- A. Stethoscope
- B. Thermometer
- C. Blood pressure cuff
- D. Sphygmomanometer
Correct Answer: B
Rationale: Pyrexia (fever) requires temperature monitoring, making a thermometer (B) essential. A stethoscope (A) assesses heart/lung sounds, not temperature. A blood pressure cuff (C) or sphygmomanometer (D) measures pressure, not fever. Choice B is correct as thermometers directly track temperature changes, a fundamental tool in nursing to manage and document febrile states accurately.
The nurse needs to take the temperature of a patient who had a cardiac arrest. Which route will the nurse use?
- A. Oral
- B. Rectal
- C. Tympanic
- D. Temporal
Correct Answer: C
Rationale: Post-cardiac arrest, tympanic (C) provides a quick, non-invasive core temperature estimate, critical for monitoring hypothermia or hyperthermia in resuscitation. Oral (A) risks inaccuracy post-arrest. Rectal (B) is invasive and slow. Temporal (D) is less reliable in emergencies. Choice C is correct, aligning with ACLS emphasis on rapid, safe temperature assessment.
The nurse is caring for an infant and is obtaining the patient's vital signs. Which artery will the nurse use to best obtain the infant's pulse?
- A. Radial
- B. Brachial
- C. Femoral
- D. Popliteal
Correct Answer: B
Rationale: In infants, the brachial artery (B) is preferred for pulse due to accessibility and strength; radial (A) is weak and hard to palpate. Femoral (C) and popliteal (D) are less practical. Choice B is correct, per pediatric norms, ensuring accurate infant pulse assessment.
The nurse is preparing to assess the blood pressure of a 3 year old. How should the nurse proceed?
- A. Use the diaphragm portion of the stethoscope to detect Korotkoff sounds.
- B. Obtain the reading before the child has a chance to 'settle down.'
- C. Choose the cuff that says 'Child' instead of 'Infant.'
- D. Explain the procedure to the child.
Correct Answer: D
Rationale: For a 3-year-old, explaining the procedure (D) reduces anxiety, improving cooperation. Diaphragm (A) is less effective than the bell for Korotkoff sounds. Pre-settling (B) risks agitation. Child cuff (C) is correct but secondary. Choice D is correct, per pediatric nursing communication strategies.
The nurse is caring for a patient whose condition is deteriorating and needs a pulse assessment. Which site should the nurse use?
- A. Radial
- B. Brachial
- C. Carotid
- D. Popliteal
Correct Answer: C
Rationale: In deteriorating patients, carotid (C) provides a strong, accessible pulse, reliable even in low perfusion, unlike radial (A) or brachial (B). Popliteal (D) is impractical. Choice C is correct, per emergency nursing standards (e.g., AHA), for critical pulse checks.
