Adult Health Nursing Quizlet Final

Correct Answer: D

Rationale: Nurse Parker functioned independently when she initiated the visit by arranging for the clergy to see patient Ximena. In this scenario, the nurse took the initiative on her own without needing approval or direction from others. She recognized the patient's request for spiritual guidance and took independent action to meet that need. Independently functioning in this context demonstrates the nurse's autonomy and ability to make decisions based on the patient's preferences and well-being.

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: A

Rationale: Acanthosis nigricans is a skin condition characterized by multiple, hyperpigmented, velvety plaques typically seen in flexural areas such as the axillae, neck, and groin. These lesions are often associated with obesity and insulin resistance. The appearance of acanthosis nigricans is distinct from other skin conditions such as seborrheic keratosis, dermatofibroma, and epidermal nevus. Acanthosis nigricans is commonly seen in conditions like obesity, type 2 diabetes, and metabolic syndrome due to the insulin resistance that leads to the overgrowth of keratinocytes.

Correct Answer: B

Rationale: When managing a conscious patient with a severe nosebleed (epistaxis), the appropriate intervention is to have the patient sit upright and lean slightly forward to prevent blood from flowing into the throat and causing choking or swallowing. Pinching the soft part of the nose just below the bony part can help apply pressure to the bleeding vessel and stop the bleeding. This maneuver also helps compress the blood vessels in the nose, promoting clot formation and stopping the bleeding. It is important not to tilt the head back as this can cause blood to flow into the throat and potentially lead to swallowing, choking, or aspiration. Packing the nose with cotton gauze should be done by medical professionals if the bleeding does not stop with direct pressure. Applying direct pressure to the forehead is not effective for managing nosebleeds; pressure should be applied to the nostrils instead.

Correct Answer: A

Rationale: Acute narrow-angle glaucoma is a medical emergency that requires timely intervention to reduce intraocular pressure. Acetazolamide (Diamox) is a medication commonly used to treat this condition as it works as a carbonic anhydrase inhibitor, reducing the production of aqueous humor in the eye. By reducing the production of aqueous humor, acetazolamide helps decrease intraocular pressure rapidly, which is crucial in managing acute narrow-angle glaucoma. Other options listed, such as Furosemide (Lasix), Atropine, and Urokinase (Abbokinase), are not typically used in the treatment of acute narrow-angle glaucoma.
