A nurse is developing a care plan for a patient prescribed bed rest as a result of a pelvic fracture. Which goal statement is realistic for the nurse to assign to this patient?
Patient will increase activity level this shift.
Patient will turn side to back to side with assistance every 2 hours.
Patient will use the walker correctly to ambulate to the bathroom as needed.
Patient will use a sliding board correctly to transfer to the bedside commode as needed.
The Correct Answer is B
A. Increasing activity level may be unrealistic for a patient on strict bed rest due to a pelvic fracture.
B. Repositioning every 2 hours is a realistic and achievable goal for a patient on bed rest to prevent complications such as pressure ulcers and maintain circulation.
C. Using a walker for ambulation may not be feasible immediately after a pelvic fracture.
D. Transferring with a sliding board may not be safe or appropriate in the early stages post-injury, especially if bed rest is required.

Correct Answer is ["A","B","C","D","F"]
Explanation
A. Applying knowledge of disease processes is essential in preventing the spread of infections and understanding transmission routes.
B. Proper disposal of supplies is crucial in minimizing the risk of cross-contamination and infection spread.
C. Checking the negative-pressure system is critical to ensure it functions properly to contain airborne pathogens.
D. Hand hygiene is a key practice in preventing infection and should be performed before and after patient contact in both scenarios.
E. This statement is misleading; while some precautions may overlap, there are specific differences that must be addressed in interventions for airborne versus contact precautions.
F. It is important for patients in airborne precautions to wear a mask during transportation to prevent the spread of infectious particles.
Correct Answer is B
Explanation
A. Ventricular filling time and diastolic filling time are not formulas used to calculate cardiac output; they pertain to the phases of the cardiac cycle.
B. Cardiac output is calculated by multiplying stroke volume (the amount of blood ejected by the heart with each beat) by heart rate (the number of beats per minute). This formula accurately reflects the overall volume of blood the heart pumps in one minute.
C. Myocardial contractility and myocardial blood flow are important factors in cardiac function but do not directly provide a formula for calculating cardiac output.
D. Preload and afterload are factors that affect stroke volume but are not used to calculate cardiac output directly.
