RN exams medical-surgical practice questions set 14

Correct answer:

The correct answer is D: Treating the fever before beginning the therapy. Fever can be a sign of infection or other serious underlying issues. Before starting the infusion, it is crucial to address the fever to prevent potential complications. The step-by-step rationale is: 1. Assess the patient's vital signs - In this case, the patient has a temperature of 101.5°F. 2. Recognize the significance of fever - Fever can indicate infection or other health concerns. 3. Prioritize patient safety - Treating the fever before starting the infusion ensures the patient's well-being. 4. Prevent potential adverse reactions - Infusing tositumomab with a fever could exacerbate the patient's condition. 5. Collaborate with the healthcare team - Once the fever is treated, the therapy can be safely initiated. Incorrect Choices: A: Holding the infusion until the patient is afebrile - This delays necessary treatment and does not address the underlying issue causing

Correct answer:

The correct answer is A: Assess the client's lung sounds and oxygenation. This is the most appropriate action because Lisinopril, an ACE inhibitor, can cause a side effect of cough due to bradykinin accumulation in the lungs. This cough can indicate potential pulmonary edema or bronchospasm. Assessing lung sounds and oxygenation can help determine the severity of the cough and any respiratory distress. It is crucial to evaluate the client's respiratory status promptly to prevent further complications. Summary of other choices: B: Instructing the client on another antihypertensive is not appropriate without assessing the current situation. C: Obtaining vital signs is important but assessing the respiratory status takes precedence due to potential respiratory distress. D: Reminding the client about the side effect of Prinivil is not sufficient; the focus should be on evaluating the current cough and its impact on the client's respiratory status.

Correct answer:

In the scenario described, the patient is experiencing refractory hypotension despite adequate fluid resuscitation, indicating the presence of septic shock. In septic shock, systemic vasodilation and vascular hyporesponsiveness contribute to hypotension. Therefore, the primary management approach is to restore vascular tone and blood pressure to maintain organ perfusion. Administering vasopressor medications (Choice A) is the crucial intervention to achieve this goal. Vasopressors, such as norepinephrine or vasopressin, constrict blood vessels and increase blood pressure, helping to stabilize the patient in septic shock. While options B and C (performing blood cultures and initiating broad-spectrum antibiotics) are important for identifying the causative pathogen and treating the infection, they are secondary to the immediate need for hemodynamic support in septic shock. Prophylactic anticoagulation (Choice D) is not the primary intervention for

Correct answer:

In a critically ill patient admitted to the ICU with acute renal failure requiring renal replacement therapy (RRT), the healthcare team should prioritize the initiation of continuous renal replacement therapy (CRRT). CRRT is preferred in critically ill patients with hemodynamic instability as it allows for slow and continuous removal of solutes and fluids, making it a safer option compared to intermittent hemodialysis. CRRT can also provide better control of volume status and electrolyte imbalances over a longer period, which is beneficial in critically ill patients who are hemodynamically unstable. Peritoneal dialysis is not commonly used in the ICU setting for acute renal failure requiring RRT, and loop diuretics are not effective in treating acute renal failure. Temporary hemodialysis catheters may also be used, but CRRT is generally preferred in critically ill patients for better hemodynamic tolerance and control of solute and fluid removal.

Correct answer:

The correct answer is D: Perform pre-oxygenation prior to suctioning. In this scenario, the increase in heart rate and irregularity could be due to hypoxia resulting from suctioning. Pre-oxygenation helps to ensure adequate oxygenation before the procedure, preventing hypoxia-induced dysrhythmias. By providing oxygen before suctioning, the nurse can minimize the risk of further complications. Choice A (Obtain a cardiology consult) is incorrect because immediate action is required to address the potential hypoxia, which can be managed by pre-oxygenation. Choice B (Suction the client less frequently) is incorrect as it does not address the immediate concern of potential hypoxia leading to dysrhythmias. Choice C (Administer an antidysrhythmic medication) is incorrect as it is not the initial intervention needed in this situation; addressing the underlying cause of potential hypoxia is essential before considering antidysrhythmic medications.

Correct answer:

The correct answer is D: Performing hand hygiene. Hand hygiene is the most effective way to prevent the spread of infection in a healthcare setting. By washing hands thoroughly and regularly, healthcare workers can reduce the transmission of pathogens between patients and themselves. This is crucial in preventing healthcare-associated infections. Raising the temperature in each client's room (Choice A) is not an effective method for preventing infection transmission. Assessing vital signs once daily (Choice B) is important for monitoring patient health but is not directly related to preventing infection. Wearing a mask for client care (Choice C) is important in certain situations, but hand hygiene is a more universal and crucial practice for infection prevention. In summary, performing hand hygiene is the priority teaching point as it is the most effective and fundamental measure in preventing infection transmission in a healthcare setting.

Correct answer:

The correct answer is B: It is a dynamic field, continually evolving through research. Immunology is constantly evolving due to new discoveries and advancements in technology. Research in immunology leads to a deeper understanding of the immune system and its interactions with pathogens, cancer, and other diseases. This ongoing evolution is essential for the development of new treatments and vaccines. Explanation of why other choices are incorrect: A: It is largely static, with few modern discoveries - This is incorrect as immunology is a rapidly advancing field with numerous breakthroughs and discoveries. C: It exclusively studies pathogen biology - This is incorrect as immunology also encompasses the study of the immune system's responses to various stimuli, not just pathogens. D: It focuses solely on innate immunity - This is incorrect as immunology covers both innate and adaptive immunity, as well as the interactions between them.

Correct answer:

The patient's presentation of recurrent episodes of sudden, severe vertigo lasting hours, along with nausea, vomiting, nystagmus, and unilateral weakness on vestibular function tests, is most consistent with vestibular neuritis. Vestibular neuritis is an inflammatory disorder of the vestibular nerve, typically viral in origin, leading to acute onset of vertigo. Patients often experience severe vertigo, imbalance, nausea, and vomiting, along with characteristic nystagmus. Unilateral weakness on vestibular function testing supports the diagnosis of vestibular neuritis, as it indicates dysfunction of one vestibular organ. Benign paroxysmal positional vertigo (BPPV) typically presents with brief episodes of vertigo triggered by changes in head position without associated unilateral vestibular weakness. Ménière's disease is characterized by recurrent episodes of vertigo associated with fluctuating hearing loss, tinnitus, and aural fullness, and

Correct answer:

Skin color primarily results from melanin, produced by melanocytes in the epidermis's stratum basale. Melanin's variants eumelanin (dark) and pheomelanin (light) absorb UV light, determining skin tone from pale to dark, with higher levels in sun-adapted populations. Carotene, a yellow-orange pigment from diet, accumulates in the stratum corneum and hypodermis, subtly tinting lighter skin but not dominating color. Haemoglobin, in dermal blood vessels, adds pink or red hues, especially in fair skin, varying with oxygenation blue in cyanosis, red when flushed. While all three contribute, melanin is the primary determinant, as its concentration and distribution dictate the skin's base color, overshadowing carotene's minor role and haemoglobin's vascular effect. Dermatological research emphasizes melanin's evolutionary and protective significance, with carotene and haemoglobin as secondary modifiers, making it the key pigment in skin coloration.
