A nurse on a Medical-Surgical unit is preparing to administer an intramuscular injection to a client. Which of the following sites can the nurse use? (Select all that apply.).
Rectus Femoris.
Vastus Lateralis.
Dorsogluteal.
Lower abdomen.
Deltoid.
Correct Answer : B,C,E
Choice A rationale:
The choice "Rectus Femoris" is not the correct answer. The rectus femoris is a muscle located in the thigh and is not a common site for intramuscular injections due to its location and proximity to important structures.
Choice B rationale:
The correct answer is "Vastus Lateralis." Choice B is the correct answer. The vastus lateralis muscle is located on the lateral aspect of the thigh and is a suitable site for intramuscular injections. It is often used in infants and young children or in adults who have limited deltoid muscle mass.
Choice C rationale:
The correct answer is "Dorsogluteal." Choice C is the correct answer. The dorsogluteal muscle, located in the buttocks, has historically been used for intramuscular injections. However, it's important to note that due to the proximity of the sciatic nerve and the potential for incorrect injection technique, this site is used less frequently now.
Choice D rationale:
The choice "Lower abdomen" is not the correct answer. The lower abdomen is not a recommended site for intramuscular injections due to the risk of injuring underlying structures and the potential for subcutaneous injection instead of intramuscular.
Choice E rationale:
The correct answer is "Deltoid." Choice E is the correct answer. The deltoid muscle, located in the upper arm, is commonly used for intramuscular injections, especially for vaccines and smaller medication volumes. However, it has a limited muscle mass and may not be suitable for larger injection volumes.

Correct Answer is B
Explanation
Choice A rationale:
Autonomy refers to a patient's right to make their own decisions about their medical care. While autonomy is an important ethical principle, it is not directly related to the situation described. The nurse providing oxygen therapy to the patient without the patient's consent is not an example of respecting autonomy.
Choice B rationale:
Beneficence is the correct choice. Beneficence is the ethical principle of doing what is best for the patient's well-being. In this situation, providing oxygen therapy to a patient experiencing difficulty in breathing aligns with the principle of beneficence. Oxygen therapy aims to improve the patient's oxygenation and alleviate respiratory distress.
Choice C rationale:
Veracity refers to truthfulness and honesty in communication. While honesty is important, it is not the primary ethical principle at play in this situation. Providing oxygen therapy to improve the patient's condition is more aligned with beneficence.
Choice D rationale:
Fidelity refers to the duty to be faithful and keep promises. While fidelity is important in maintaining trust between healthcare providers and patients, it is not the primary principle relevant here. The priority is to address the patient's immediate health needs through appropriate interventions like oxygen therapy.
Correct Answer is D
Explanation
Choice A rationale:
Pneumonia is not likely to be the correct answer. Pneumonia is often characterized by productive cough, fever, chest pain, and increased tactile fremitus due to consolidation of lung tissue. The presence of barrel chest, decreased tactile fremitus, and hyperresonant percussion sounds is not consistent with pneumonia.
Choice B rationale:
Atelectasis is not the most likely option. Atelectasis refers to collapsed or partially collapsed lung tissue, which can lead to decreased breath sounds, dullness to percussion, and decreased tactile fremitus. The symptoms mentioned in the scenario, such as prolonged expiration, wheezes, and barrel chest, are not indicative of atelectasis.
Choice C rationale:
Pleural effusion is not the most suitable choice. Pleural effusion usually presents with decreased breath sounds, dullness to percussion, and decreased tactile fremitus over the affected area due to fluid accumulation in the pleural space. The hyperresonant percussion sounds and the presence of wheezes and rhonchi do not align with pleural effusion.
Choice D rationale:
Emphysema is the most likely disorder based on the given symptoms. Barrel chest (increased anterior-posterior chest diameter), limited lung expansion, decreased tactile fremitus, hyperresonant percussion sounds, prolonged expiration, wheezes, and rhonchi are characteristic findings of emphysema. This condition involves damage to the alveoli and their supporting structures, leading to air trapping, reduced lung elasticity, and obstructed airflow. The patient's use of accessory muscles to breathe further suggests a chronic obstructive pulmonary disease (COPD) like emphysema.
