Adult Health Nursing Quizlet Final

Correct Answer: B

Rationale: Albuterol, also known as salbutamol, is a beta-adrenergic agonist medication commonly used for the treatment of conditions such as asthma and COPD. As a beta-adrenergic agonist, albuterol binds to beta-2 adrenergic receptors in the lungs, causing bronchodilation, which helps to relieve bronchospasms and improve airflow to the lungs. This action leads to the relaxation of smooth muscle in the airways, thus making breathing easier for patients with COPD or asthma. Anticholinergics, corticosteroids, and methylxanthines have different mechanisms of action and are not directly related to the pharmacological action of albuterol in COPD treatment.

Correct Answer: B

Rationale: The most appropriate nursing diagnosis for the individual described is "Ineffective individual coping." This is because the individual has been facing challenges in both academic (failing math class) and personal (substance dependence) aspects of his life. The repeated failures in his math class and the substance dependence for three years indicate that he might be struggling to cope with stressors and challenges in his life effectively. By identifying this nursing diagnosis, the nurse can focus on helping the individual develop effective coping strategies to manage and overcome these difficulties.

Correct Answer: B

Rationale: The nurse's priority when a patient appears confused and disoriented during a consultation is to provide clear and simple explanations and assess for any underlying causes of confusion. It is essential to ensure that the patient understands the information being provided and to address any potential reasons for the confusion, such as medication side effects, medical conditions, or cognitive impairment. Ignoring the patient's confusion or assuming they cannot understand can lead to misunderstandings, errors in care, and ultimately jeopardize the patient's well-being. It is crucial to approach the situation with empathy, patience, and a focus on ensuring effective communication and understanding between the nurse and the patient.

Correct Answer: D

Rationale: Fidelity is a principle of ethics that relates to being faithful or loyal to one's commitments and responsibilities. When Nurse Pat promises to assist the post-surgical patient with ambulation after carrying out the physician's order, she is demonstrating fidelity by honoring her commitment to the patient. This principle highlights the importance of keeping promises, being reliable, and maintaining trust in the nurse-patient relationship.

Correct Answer: C

Rationale: Intracerebral hemorrhage is characterized by bleeding directly into the brain parenchyma, leading to the sudden onset of severe headache, vomiting, altered mental status, and neurological deficits. The hyperdense lesion seen on imaging is caused by the presence of blood within the brain tissue. This condition is often associated with hypertension and can be life-threatening if not promptly diagnosed and managed. Subdural hematoma is an accumulation of blood between the brain and its outermost covering (dura mater), typically presenting with a slower onset of symptoms compared to intracerebral hemorrhage. Subarachnoid hemorrhage involves bleeding into the space between the arachnoid membrane and the pia mater (subarachnoid space), commonly caused by the rupture of an aneurysm. Ischemic stroke results from the blockage of a blood vessel supplying the brain, leading to a lack of oxygen and nutrients to
