The correct method for determining the vastus lateralis site for I.M. injection is to:

Correct Answer: D

Rationale: Failed to generate a rationale of 500+ characters after 5 retries.

Correct Answer: D

Rationale: A patient being kept off food and fluids before surgery can lead to dehydration. Dehydration can cause a slight increase in body temperature, which could explain the elevated oral temperature reading of 99.8°F (37.7°C) in this scenario. Infections are more likely to cause higher fevers, hypothermia would present with a lower temperature, and anxiety typically does not directly affect body temperature in this manner.

Correct Answer: C

Rationale: Failed to generate a rationale of 500+ characters after 5 retries.

Correct Answer: C

Rationale: In this scenario, the new head nurse should discuss the problem with her supervisor. This is the most appropriate action as the supervisor is in a position to address staffing concerns effectively and make necessary changes. Complaining to fellow nurses may not lead to a solution, waiting may exacerbate the issue, and demanding staff rotation without proper discussion is not a collaborative approach to resolving the problem.

Correct Answer: D

Rationale: All the listed interventions are essential for promoting patient safety. Assessing the patient's ability to ambulate and transfer helps prevent falls, demonstrating the signal system ensures effective communication in emergencies, and checking the patient's identification band aids in accurate identification and treatment. By combining these interventions, healthcare providers can enhance patient safety and quality of care.

Correct Answer: B

Rationale: Vitamin C requirements are increased during infancy, childhood, and pregnancy due to growth and development. However, during young adulthood, the body generally requires a consistent amount of Vitamin C as it is not undergoing rapid growth or physiological changes that necessitate an increase in Vitamin C intake.

Correct Answer: D

Rationale: Palpating the midclavicular line is the correct technique for assessing the apical pulse. The apical pulse is located at the point of maximal impulse (PMI), which is typically at the fifth intercostal space at the midclavicular line. This technique allows healthcare providers to accurately assess the heart rate and rhythm by listening to the heart sounds directly at this point.

Correct Answer: A

Rationale: The patient's symptoms of shortness of breath, orthopnea, thick, tenacious secretions, and a dry hacking cough all point towards a potential airway clearance issue. This makes option A, 'Ineffective airway clearance related to thick, tenacious secretions,' the most appropriate nursing diagnosis. It directly addresses the thick secretions and suggests a potential cause of the breathing difficulty the patient is experiencing.

Correct Answer: D

Rationale: Preserving skin integrity plays a key role in breaking the chain of infection by eliminating the portal of entry for pathogens. When the skin is intact, it acts as a natural barrier that prevents pathogens from entering the body. By maintaining skin integrity through proper hygiene and wound care, the risk of infection is significantly reduced, disrupting the cycle of infection transmission.
