Which of the following actions is recommended for controlling severe external bleeding from an extremity?

Correct Answer: C

Rationale: When controlling severe external bleeding from an extremity, the recommended action is to apply direct pressure with a sterile dressing. Direct pressure helps to stop the bleeding by promoting clot formation and reducing blood flow from the wound. This method is effective in most cases and should be the first response to control bleeding. Elevating the extremity above the level of the heart can be helpful in some cases, but direct pressure is the initial recommended action. Applying a tourniquet proximal to the injury site should only be done as a last resort when other methods are not successful, as it can lead to complications such as tissue damage. Removing any impaled objects can actually worsen the bleeding and should be avoided unless necessary for immediate life-saving measures.

Correct Answer: A

Rationale: Nurse Vera should focus on the last menstrual period when assessing the health condition of the pregnant patient because it is crucial for determining the estimated due date of the pregnancy. Knowing the date of the last menstrual period allows healthcare providers to calculate the gestational age of the fetus, monitor the progress of the pregnancy, and identify any potential issues or complications that may arise. Additionally, the last menstrual period is necessary for accurate dating of the pregnancy and scheduling prenatal care visits and screenings. By focusing on the last menstrual period, Nurse Vera can gather important information that will guide the management and care of the pregnant patient.

Correct Answer: C

Rationale: The described clinical presentation of a yellowish-white spot on the cornea with a ring of inflammation, along with branching, filamentous opacities extending from the corneal lesion, is highly suggestive of fungal keratitis. Fungal keratitis is commonly caused by filamentous fungi such as Fusarium and Aspergillus species. The characteristic finding of branching, filamentous opacities seen on slit-lamp examination is classic for fungal infections of the cornea. It is important to promptly diagnose and treat fungal keratitis since delayed or inadequate management can result in vision-threatening complications.

Correct Answer: B

Rationale: A cohort study design would be appropriate in this scenario. Cohort studies follow a group of individuals over a period of time to assess how their current health status, personal characteristics, and potential risk factors may contribute to the development of certain outcomes or diseases. By collecting data at different time points on the same group of individuals, cohort studies allow researchers to establish associations between exposures and outcomes, providing valuable information on causality. In this case, using a cohort study design would allow for a comprehensive examination of how various factors impact health outcomes over time.

Correct Answer: C

Rationale: In ALS (Amyotrophic Lateral Sclerosis), communication difficulties may occur as the disease progresses and affects the muscles responsible for speech. It is crucial to initiate early measures to assist the patient in communicating effectively. Using pre-signals before the loss of speech can be helpful in maintaining communication with the patient. These pre-signals can include gestures, writing tools, communication boards, or technology-assisted communication devices. By introducing and practicing these pre-signals early on, the patient can adapt and utilize alternative communication methods before the loss of speech becomes more challenging. This proactive approach can significantly improve the patient's ability to communicate and maintain a sense of connection with others.

Correct Answer: B

Rationale: Pain is best described as a subjective unpleasant experience because it is unique to each individual and is influenced by a variety of factors including emotional, psychological, and cultural elements. Pain cannot be objectively measured or quantified, and therefore it is considered a subjective experience that is reported by the person experiencing it. This is why pain is often assessed using self-report scales and tools to capture the individual's perception of their pain intensity and quality.

Correct Answer: C

Rationale: The best approach in dealing with a nurse who is resistant to change and not actively participating is to communicate and encourage verbalizing feelings about the change. By talking with the nurse and allowing them to express their concerns and feelings, you can address any underlying issues that may be causing the resistance. This approach can help build trust, improve communication, and ultimately increase the nurse's engagement in the change process. Coercion (Choice A) can create negative feelings and resistance, while ignoring the nurse's resistance (Choice D) will not resolve the issue. Providing positive rewards (Choice B) may be helpful but may not address the underlying reasons for resistance. Communication is key in addressing resistance to change and fostering a positive, open environment for all involved.

Correct Answer: B

Rationale: Refeeding syndrome is a potentially dangerous condition that can occur in malnourished individuals when nutrition is reintroduced too quickly. It is characterized by shifts in electrolytes, fluid imbalance, and metabolic abnormalities. Monitoring for decreased bowel sounds, nausea, bloating, and abdominal distention is the priority action to prevent complications associated with refeeding syndrome. These symptoms can indicate gastrointestinal issues such as ileus or overfeeding, which can lead to further complications. Early recognition and intervention can help prevent serious consequences of refeeding syndrome.

Correct Answer: B

Rationale: Elevating the head of the bed to improve respiratory mechanics is the most appropriate intervention for managing paroxysmal nocturnal dyspnea in a patient with end-stage heart failure. By keeping the head of the bed elevated, gravity helps reduce the pooling of fluid in the lungs, making it easier for the patient to breathe and reducing dyspnea. This strategy can help improve oxygenation and decrease the sensation of breathlessness, providing relief for the patient. Administering diuretic medications (Option A) can also be beneficial to reduce fluid overload, although positioning remains a key intervention. Encouraging the patient to sleep in a reclined position (Option C) can help alleviate symptoms, but specifically elevating the head of the bed is a more targeted approach. Referring the patient to a sleep specialist (Option D) may not be necessary at this time, as the primary concern is managing the acute symptom of paroxysmal nocturnal dyspnea
