The first standard-step-in oxygen therapy that the nurse should do is which of the following?

Correct Answer: D

Rationale: Before initiating any oxygen therapy, it is crucial for the nurse to first assess the patient's condition. This step allows the nurse to determine the patient's oxygen saturation levels, respiratory rate, lung sounds, and overall respiratory status. Understanding the patient's baseline condition helps in selecting the appropriate oxygen delivery method and flow rate that will best meet the patient's needs. Additionally, assessing the patient's condition allows the nurse to monitor the effectiveness of the oxygen therapy and make any necessary adjustments throughout the treatment process. Therefore, assessing the patient's condition is the necessary first step in providing safe and effective oxygen therapy.

Correct Answer: C

Rationale: The presentation described in the question (sensation of fullness and pressure in the left ear, hearing loss, occasional tinnitus, retracted tympanic membrane with decreased mobility on pneumatic otoscopy) is suggestive of serous otitis media, also known as otitis media with effusion. Serous otitis media occurs when fluid accumulates in the middle ear without signs of infection. This buildup of fluid in the middle ear space can cause the tympanic membrane to retract and reduce its mobility on pneumatic otoscopy.

Correct Answer: B

Rationale: Adenomyosis is a condition characterized by the presence of endometrial tissue within the myometrium (muscle wall) of the uterus. It can present with symptoms such as cyclic pelvic pain, dysmenorrhea (painful periods), and infertility. On pelvic examination, the uterus may be retroverted (tilted backward) and enlarged due to the presence of adenomyotic nodules within the uterine muscle. Adenomyosis can also cause heavy menstrual bleeding (menorrhagia). Endometriosis, on the other hand, involves the presence of endometrial tissue outside the uterus and can cause similar symptoms but is less likely to result in uterine enlargement or retroversion. Leiomyomas (uterine fibroids) are benign tumors of the uterine muscle and can also cause pelvic pain and abnormal uterine enlargement but are less likely to be associated with dysmenorrhea and infertility

Correct Answer: A

Rationale: Molluscum contagiosum is a viral skin infection caused by the poxvirus. It typically presents as multiple, flesh-colored, dome-shaped papules with a central umbilication (dimple or depression in the center) on the skin. These lesions are often found on the trunk and extremities and can persist for several months. Molluscum contagiosum is commonly seen in children but can also occur in adults, especially those with weakened immune systems. The lesions are usually asymptomatic but can become inflamed or itchy in some cases. Treatment options include observation, topical therapies, cryotherapy, or curettage.

Correct Answer: D

Rationale: Advocacy is the ethical principle that the nurse is responsible for providing all patients with caring attention and information, despite the reaction of the patient. Advocacy involves supporting and speaking up for the patient's best interests, ensuring they receive the care and information they need to make informed decisions about their health and well-being. Providing caring attention and information is essential in advocating for the patient's autonomy and well-being, even if the patient may not initially appreciate or react positively to these efforts.

Correct Answer: C

Rationale: Total Parenteral Nutrition (TPN) is a method of providing nutrition to patients who cannot or should not obtain their nutrition through regular oral intake. The primary goals of TPN include promoting weight gain, improving nutritional status, maintaining muscle mass, and establishing nitrogen balance. These goals are crucial to support the overall health and well-being of the patient receiving TPN. Enhancing the healing process is an important aspect of TPN as well, but it is not considered one of the primary goals as weight gain, nutritional status, muscle mass, and nitrogen balance are typically the immediate priorities when administering TPN.

Correct Answer: D

Rationale: An elevation of blood pressure would warrant stoppage of pills. High blood pressure, or hypertension, in a 4-year-old child is abnormal and needs prompt medical attention. Giving pills without monitoring or stopping them if blood pressure is elevated can lead to serious health complications. It is important to address the underlying cause of high blood pressure in a child, which may require further evaluation and management by a healthcare provider.

Correct Answer: D

Rationale: The presentation of sudden-onset severe headache, vomiting, and altered mental status, along with the presence of a berry-shaped aneurysm on imaging, point towards a diagnosis of subarachnoid hemorrhage. The most common cause of a subarachnoid hemorrhage is the rupture of a saccular (berry) aneurysm, which commonly occurs at the junction of the anterior communicating artery and anterior cerebral artery. The sudden headache is often described as the "worst headache of my life" and is typically associated with nausea and vomiting. Altered mental status may be present due to the effects of increased intracranial pressure and possible associated brain injury. It is important to promptly diagnose and manage subarachnoid hemorrhage to prevent complications such as vasospasm, rebleeding, and ischemic deficits.

Correct Answer: A

Rationale: Assisting the mother into a hands-and-knees position should be prioritized to facilitate fetal rotation and optimize labor progress in the case of persistent occiput posterior fetal position. This position helps in promoting fetal rotation to a more favorable position for delivery by allowing the baby's head to move into the anterior position. It can help alleviate back pain and may help reduce the duration of labor. This simple maneuver can sometimes correct the malposition without the need for interventions like instrumental delivery. It is a non-invasive and effective technique that can be easily implemented by healthcare providers to support the progression of labor.
