A patient with obstructive sleep apnea (OSA) presents with excessive daytime sleepiness, loud snoring, and witnessed apneic episodes during sleep. Which of the following interventions is most appropriate for managing OSA and improving symptoms?

Correct Answer: B

Rationale: CPAP therapy is considered the gold standard treatment for obstructive sleep apnea (OSA) and is the most appropriate intervention for managing OSA and improving symptoms. CPAP therapy involves using a machine that delivers a continuous flow of air through a mask worn over the nose or mouth during sleep. This air pressure helps keep the airway open, preventing the collapse that causes apneas and snoring during sleep.

Correct Answer: C

Rationale: The esophagus is responsible for propelling food from the oral cavity to the stomach through a series of coordinated muscular contractions. These contractions are known as peristalsis. The esophagus is a muscular tube connecting the throat (pharynx) to the stomach and plays a crucial role in moving food bolus from the mouth to the stomach for digestion. The tongue helps in the chewing and swallowing of food, the pharynx is involved in the passage of food and air, and the epiglottis helps prevent food from entering the airways during swallowing. However, it is the esophagus that actively moves the food to the stomach.

Correct Answer: B

Rationale: The type of incontinence that Patient Tita is demonstrating, with involuntary loss of urine occurring as a result of activities such as sneezing, coughing, or changing position, is known as stress incontinence. Stress incontinence occurs when there is increased pressure on the bladder, causing the sphincter muscles to weaken and leading to urine leakage. Activities that physically stress or put pressure on the bladder, such as the ones mentioned, can trigger episodes of stress incontinence.

Correct Answer: A

Rationale: The most appropriate nursing diagnosis for this patient would be "Self-care deficit related to neuromuscular impairment." This diagnosis is supported by the information provided, which indicates that the patient is experiencing neuromuscular impairment that is likely affecting their ability to perform self-care activities. A self-care deficit diagnosis is relevant when a patient is unable to perform activities of daily living independently due to physical or cognitive limitations. In this case, the neuromuscular impairment is likely impacting the patient's ability to engage in self-care tasks, such as feeding, grooming, bathing, and dressing. By identifying and addressing this self-care deficit, the healthcare team can help the patient maintain optimal functioning and independence despite their neuromuscular impairment.

Correct Answer: C

Rationale: Colposcopy with biopsy is the most appropriate diagnostic test for evaluating a woman with suspected cervical dysplasia. Colposcopy is a procedure in which a special magnifying instrument called a colposcope is used to examine the cervix for any abnormal areas. If abnormal tissue is identified during colposcopy, a biopsy will be taken to confirm the presence of cervical dysplasia and determine the severity. This allows for a more accurate diagnosis and appropriate management of the condition. Pap smear, although a screening test for cervical dysplasia, may not provide a definitive diagnosis and may require further evaluation with colposcopy and biopsy. Endometrial biopsy and transvaginal ultrasound are not indicated for evaluating cervical dysplasia specifically.

Correct Answer: C

Rationale: If the nurse observes an unusual odor emanating from the surgical site during surgery, it is important to inform the surgeon immediately and assess for signs of infection. Changes in odor can sometimes be an early sign of infection, which requires prompt attention and intervention. By communicating with the surgeon and conducting a thorough assessment, the nurse can help ensure the timely detection and management of any potential complications, such as infection, that may be affecting the patient's surgical outcome. Prompt action in response to unusual observations is crucial to maintaining patient safety and well-being during surgical procedures.

Correct Answer: B

Rationale: Encouraging the patient to practice controlled coughing techniques would be the most appropriate intervention to address the symptoms of chronic cough and excessive sputum production in a patient with end-stage COPD receiving palliative care. Controlled coughing techniques can help the patient effectively clear respiratory secretions and improve airway clearance without the need for additional medications or interventions. This approach focuses on optimizing the patient's ability to manage their symptoms and maintain comfort, which aligns with the goals of palliative care. Administering bronchodilator medications, prescribing mucolytic medications, or referring the patient to a respiratory therapist for breathing exercises may have limited effectiveness in this advanced stage of the disease, and controlled coughing techniques would be a more practical and patient-centered approach to symptom management.

Correct Answer: B

Rationale: Offering reassurance and encouragement to the patient demonstrates therapeutic communication by the nurse. In this situation, the nurse shows empathy and understanding towards the patient's concerns about the upcoming surgical procedure, which can help alleviate anxiety and build trust. Providing reassurance and encouragement can help the patient feel supported and understood, creating a positive and therapeutic interaction between the nurse and the patient. This approach fosters open communication and helps establish a therapeutic nurse-patient relationship, which is essential for effective patient care.

Correct Answer: A

Rationale: The patient is presenting with chest pain that worsens with exertion and improves with rest, which is characteristic of stable angina. Additionally, ST-segment depression on ECG is a common finding in patients with stable angina. Stable angina is typically caused by coronary artery disease, which leads to partial obstruction of the coronary arteries resulting in inadequate blood flow to the heart muscle during periods of increased demand (such as exertion). The chest pain is usually predictable and reproducible, occurring with similar intensity and duration during episodes of exertion. Rest or nitroglycerin can help relieve the symptoms by increasing coronary blood flow. It is important to differentiate stable angina from unstable angina and acute myocardial infarction, which have different management and prognostic implications.
