Which of the following procedures would be MOST helpful to Nurse Victor to confirm the underlying cause of cardiogenic shock?

Correct Answer: C

Rationale: Monitoring cardiac enzymes would be most helpful to Nurse Victor to confirm the underlying cause of cardiogenic shock. Cardiac enzymes are specific markers in the blood that indicate damage to the heart muscle, such as troponin and creatine kinase-MB (CK-MB). When a patient experiences cardiogenic shock, there is usually damage to the heart muscle which leads to the release of these enzymes into the bloodstream. Monitoring cardiac enzymes can help confirm if the cause of cardiogenic shock is related to myocardial infarction or another cardiac issue. This information is crucial for determining the appropriate treatment and management plan for the patient. Monitoring pulmonary artery pressure, mean arterial pressure, and central venous pressure may provide important hemodynamic information but may not directly confirm the underlying cause of cardiogenic shock.

Correct Answer: B

Rationale: Being assertive means expressing one's thoughts, beliefs, and feelings in a confident and respectful manner while also considering the perspective of others. It does not involve pushing control on others. Assertive individuals do not impose their beliefs on others but express themselves clearly and confidently, respecting the opinions of others. So, standing up for what one believes in can be assertive, but pushing control on others is not a characteristic of assertiveness.

Correct Answer: C

Rationale: When the nurse collects data at one point in time, it is referred to as a cross-sectional study. Cross-sectional studies are observational research designs that provide a snapshot of a population or a sample at a specific point in time. This type of study can help identify associations or relationships between variables at a single time point but cannot establish causality or determine changes over time. In contrast, time series involve collecting data over multiple time points, longitudinal studies follow individuals or samples over time to track changes or outcomes, and crossover studies involve multiple interventions or treatments over different periods.

Correct Answer: C

Rationale: Rabies is a viral disease that affects the central nervous system. It is primarily transmitted through the bite of an infected animal, such as dogs, bats, raccoons, and foxes. The causative agent of rabies is the rabies virus, specifically from the genus Lyssavirus. Once the virus enters the body, it spreads through the nervous system to the brain, leading to severe neurological symptoms and, if left untreated, is almost always fatal. This is why prompt medical attention and vaccination following an animal bite are crucial in preventing the development of rabies in humans.

Correct Answer: D

Rationale: When determining the existence of malpractice, intent is not considered as a factor. Malpractice typically involves unintentional actions or negligence rather than a deliberate intent to cause harm. The key factors that are usually considered in a malpractice case include duty (a legal obligation to provide a certain standard of care), causation (the link between the provider's actions and the patient's injury), and the existence of an injury resulting from the provider's actions or omissions. Intent does not play a direct role in malpractice cases, as they are focused on the standard of care provided by the healthcare professional and the harm caused as a result.

Correct Answer: A

Rationale: The development of autoantibodies such as antinuclear antibodies (ANA) and anti-double-stranded DNA (anti-dsDNA) antibodies in systemic lupus erythematosus (SLE) is primarily attributed to a loss of self-tolerance. Self-tolerance refers to the immune system's ability to recognize and differentiate self-antigens from foreign antigens. In individuals with SLE, there is a breakdown in immune tolerance mechanisms, leading to the production of autoantibodies against self-antigens like nuclear components (e.g., DNA, RNA, histones). This loss of self-tolerance results in the immune system targeting and attacking its tissues, leading to the systemic inflammation and tissue damage characteristic of SLE. The presence of elevated levels of ANA and anti-dsDNA antibodies in this patient suggests an autoimmune response against nuclear material, further supporting the role of self-tolerance breakdown in SLE

Correct Answer: A

Rationale: Nonverbal communication is as strong in conveying information because the nurse can effectively interpret and understand gestures made by the individual they are interacting with. Gestures such as hand movements, facial expressions, eye contact, and body posture can communicate a lot of information without the use of words. By observing these nonverbal cues, nurses can better comprehend the emotions, needs, and feelings of their patients or colleagues, leading to more effective communication and overall better care. Nonverbal communication, including gestures, plays a significant role in creating a holistic understanding of individuals' messages beyond just words.

Correct Answer: A

Rationale: Nurse Adalynn explains to the mothers that early indication for hypovolemia caused by postpartum hemorrhage is an increasing pulse and decreasing blood pressure. Hypovolemia is a condition where there is a decreased volume of circulating blood in the body, often characterized by fluid loss such as through bleeding. As blood volume decreases, the heart rate increases in an attempt to maintain adequate perfusion to organs and tissues. This results in an elevated pulse rate. Additionally, as the blood volume decreases, the blood pressure may drop due to the reduced amount of blood being pumped around the body. Therefore, monitoring for an increasing pulse and decreasing blood pressure is crucial in detecting hypovolemia early, allowing for prompt intervention to prevent further complications.

Correct Answer: A

Rationale: The patient presents with gradual, painless visual field loss in both eyes, particularly in the peripheral vision, which is characteristic of glaucoma. The elevated intraocular pressure (IOP) on tonometry further supports a diagnosis of glaucoma. Open-angle glaucoma is the most common type of glaucoma and typically presents insidiously with a slow progression of vision loss. In open-angle glaucoma, the drainage angle of the eye remains open but becomes less efficient over time, leading to increased intraocular pressure and optic nerve damage. This results in peripheral visual field loss. Closed-angle glaucoma, on the other hand, presents more acutely with sudden eye pain, redness, and blurred vision due to a sudden increase in intraocular pressure from a blocked drainage angle. Age-related macular degeneration and diabetic retinopathy typically do not present with elevated IOP or peripheral visual field loss.
