Adult Health Nursing First Chapter Quizlet

Correct Answer: B

Rationale: Oxybutynin is a medication commonly used for the management of overactive bladder (OAB) symptoms such as urinary urgency and frequency. It belongs to a class of medications known as anticholinergics, which work by relaxing the bladder muscles and reducing bladder spasms. By doing so, it helps to decrease the symptoms of OAB, including frequent urination, sudden urges to urinate, and leakage. Oxybutynin can be taken orally in tablet form, as a transdermal patch, or as a gel, providing various options for patients based on their preferences and needs. Overall, oxybutynin is an effective treatment option for individuals experiencing overactive bladder symptoms.

Correct Answer: C

Rationale: The nurse should always keep Tensilon (Edrophonium) at the bedside of a client with myasthenia gravis. Tensilon is a fast-acting cholinesterase inhibitor that can be used for the diagnosis and emergency treatment of myasthenia crisis. It helps improve muscle strength temporarily by increasing the levels of acetylcholine at the neuromuscular junction. Administering Tensilon can help differentiate between a myasthenic crisis (marked improvement in muscle strength) and a cholinergic crisis (no improvement or worsening of muscle weakness). Keeping Tensilon at the bedside allows for prompt administration in case of a myasthenic crisis.

Correct Answer: A

Rationale: Following total hip arthroplasty (THA), patients are at an increased risk of developing deep vein thrombosis (DVT) due to factors such as immobility, surgery-related vascular damage, and hypercoagulability. DVT refers to the formation of blood clots in the deep veins, typically in the lower extremities. These clots can break loose and travel to the lungs, causing a potentially life-threatening condition called pulmonary embolism (PE). Therefore, monitoring for signs and symptoms of DVT is crucial in the immediate postoperative period to promptly detect and prevent the development of complications such as PE. Common signs of DVT include leg swelling, pain, warmth, and redness. Additionally, healthcare providers may employ preventive measures such as early ambulation, compression stockings, and anticoagulant therapy to reduce the risk of DVT post-THA surgery.

Correct Answer: D

Rationale: The principle of beneficence emphasizes the duty to do good and act in the best interest of others. By ensuring that all necessary supplies and medicines are available for the care of the community, Nurse Erica is practicing beneficence. She is fulfilling her obligation to promote the health and well-being of the community members by providing them with the resources they need for their care. This demonstrates her commitment to doing good and acting in a way that benefits those under her care, which aligns with the principle of beneficence in nursing practice.

Correct Answer: A

Rationale: The sudden onset of severe vertigo, nausea, vomiting, and nystagmus in a patient with a recent upper respiratory tract infection is highly suggestive of vestibular neuritis. Vestibular neuritis is typically caused by inflammation of the vestibular nerve, often following a viral infection such as an upper respiratory tract infection. This condition presents with acute, severe, continuous vertigo without associated hearing loss. The presence of nystagmus, along with the absence of hearing loss, helps differentiate vestibular neuritis from Meniere's disease (which typically presents with episodic vertigo, hearing loss, and tinnitus) and acoustic neuroma (which presents with gradual onset of symptoms including unilateral hearing loss, tinnitus, and imbalance). Benign paroxysmal positional vertigo (BPPV) typically presents with brief episodes of vertigo triggered by specific head movements, rather than the continuous vertigo seen in this case.
