The nurse is having difficulty hearing his patient’s apical pulse with his stethoscope. Which action will help the nurse hear the heartbeat more clearly?
Making sure that the earpieces fit loosely in the nurse’s ear canals
Utilizing a stethoscope with the longest possible tubing
Placing the diaphragm firmly against the patient’s skin
Positioning the bell very lightly over the patient’s sternum
The Correct Answer is C
Choice A reason: This is incorrect. Making sure that the earpieces fit loosely in the nurse’s ear canals will not help the nurse hear the heartbeat more clearly. Loose earpieces can let in ambient noise and reduce the sound quality.
Choice B reason: This is incorrect. Utilizing a stethoscope with the longest possible tubing will not help the nurse hear the heartbeat more clearly. Long tubing can reduce the sound transmission and create interference.
Choice C reason: This is correct. Placing the diaphragm firmly against the patient’s skin will help the nurse hear the heartbeat more clearly. The diaphragm is the flat circular part of the chest piece that is used to listen to low-pitched sounds, such as the heart. Firm pressure creates a good seal and blocks out external noise.
Choice D reason: This is incorrect. Positioning the bell very lightly over the patient’s sternum will not help the nurse hear the heartbeat more clearly. The bell is the small cup-shaped part of the chest piece that is used to listen to high-pitched sounds, such as the lungs. Light pressure is needed to avoid activating the diaphragm, but the sternum is not the best location to listen to the apical pulse.

Correct Answer is C
Explanation
Choice A reason: This is an incorrect choice because the hospice RN works closely with the patient’s daughter to ensure that the patient’s dying requests are met is not a patient assignment that demonstrates the concept of team nursing. Team nursing is a model of care in which a team of healthcare providers, including RNs, licensed practical nurses (LPNs), nursing assistants, and other support staff, work together to provide care for a group of patients¹. Working closely with the patient’s daughter is an example of family-centered care, not team nursing.
Choice B reason: This is an incorrect choice because the RN cares for the same five patients every day during their stay following joint replacement surgery is not a patient assignment that demonstrates the concept of team nursing. Team nursing is a model of care in which a team of healthcare providers, including RNs, licensed practical nurses (LPNs), nursing assistants, and other support staff, work together to provide care for a group of patients¹. Caring for the same five patients every day is an example of primary nursing, not team nursing.
Choice C reason: This is the correct choice because the RN, the LPN, and the nursing assistant work together to provide all the care needed by eight patients for the shift is a patient assignment that demonstrates the concept of team nursing. Team nursing is a model of care in which a team of healthcare providers, including RNs, licensed practical nurses (LPNs), nursing assistants, and other support staff, work together to provide care for a group of patients¹. Each member of the team performs specific duties appropriate to their role to provide total patient care. Teams may include licensed practical nurses (LPNs) and unlicensed assistive personnel (UAP) that are supervised by a registered nurse (RN). Less experienced, or non-critical care RNs, may be assigned to a team in a critical care unit led by an experienced critical care RN. Each team member plays a vital role.
Choice D reason: This is an incorrect choice because the RN coordinates care of the patient with the physician assistant to ensure that the clinical pathway is followed is not a patient assignment that demonstrates the concept of team nursing. Team nursing is a model of care in which a team of healthcare providers, including RNs, licensed practical nurses (LPNs), nursing assistants, and other support staff, work together to provide care for a group of patients¹. Coordinating care of the patient with the physician assistant is an example of interprofessional collaboration, not team nursing.
Correct Answer is D
Explanation
Choice A reason: This is incorrect. The antipyretic medication will not inhibit bacterial growth within the culture tubes. Antipyretics are medications that reduce fever by affecting the hypothalamus, the part of the brain that regulates body temperature. They do not have any antibacterial effect.
Choice B reason: This is incorrect. Venous distension is not greater because of fluid retention from hyperthermia. Venous distension is the swelling of the veins due to increased pressure or volume of blood. Hyperthermia is the condition of having a body temperature above the normal range. It can cause dehydration, not fluid retention.
Choice C reason: This is incorrect. Elevated temperatures do not slow metabolic rate and improve blood oxygenation. Elevated temperatures increase metabolic rate and demand more oxygen. This can lead to tissue hypoxia, acidosis, and organ damage.
Choice D reason: This is correct. The causative organism is most prevalent during a spike in temperature. A spike in temperature is a sudden rise in body temperature that indicates an infection. Drawing a blood culture before giving an antipyretic medication can help identify the type and number of bacteria in the blood. This can guide the appropriate antibiotic therapy and monitor the response to treatment.
