Extract:
Question 1 of 5
A nurse caring for a client with acute peritonitis reviews the physician's orders. The orders include an NPO diet, insertion of a nasogastric tube set to low intermittent suction, and IV fluids at 50 mL per hour. When asked why he will need the NG tube, what is the nurse's best reply?
Correct Answer: D
Rationale: Reason: This is incorrect because administering medications and electrolytes is not the primary purpose of inserting a nasogastric tube for a client with acute peritonitis. Medications and electrolytes can be given through other routes, such as IV or oral. Reason: This is incorrect because dilating the stomach as a presurgical preparation is not a relevant Reason for inserting a nasogastric tube for a client with acute peritonitis. Dilating the stomach may be done before some types of gastric surgery, but it does not apply to peritonitis. Reason: This is incorrect because stating that you will not be able to eat for several days is not an adequate explanation for inserting a nasogastric tube for a client with acute peritonitis. This statement does not address the rationale or the benefits of the procedure. It may also cause anxiety and resentment in the client. Reason: This is the correct choice because removing secretions and decompressing the stomach is the main Reason for inserting a nasogastric tube for a client with acute peritonitis. Peritonitis is an inflammation of the peritoneum, the membrane that lines the abdominal cavity. It can cause abdominal distension, pain, nausea, and vomiting. A nasogastric tube can suction out the gastric contents and reduce the pressure and irritation in the abdomen.
Question 2 of 5
A client receiving parenteral nutrition by central venous access reports feeling unwell. The nurse assesses the client and suspects that the central line has become infected. Which of the following findings indicate that the client has developed a systemic infection? Select all that apply.
Correct Answer: B,E,F
Rationale: Purulent drainage, leukocytosis, and fever indicate a systemic infection, as they reflect bacterial invasion and immune response spreading beyond the local site.
Question 3 of 5
A nurse is caring for a client who is experiencing Cushing's Triad following a subdural hematoma. Which of the following manifestations will the nurse expect to find? (Select all that apply.)
Correct Answer: B,D,F
Rationale:
Choice A Reason: Slow even breathing is not a sign of Cushing's Triad, which is a late indicator of increased intracranial pressure (ICP). The breathing pattern may be altered due to brainstem compression, but not necessarily slow or even.
Choice B Reason: This is a correct answer because bradycardia and bounding pulse are part of Cushing's Triad, which reflects an increased vagal tone and decreased cardiac output due to increased ICP.
Choice C Reason: Systolic hypotension with a narrowing pulse pressure is not a sign of Cushing's Triad, which involves an increased systolic blood pressure and a widened pulse pressure due to increased ICP. Hypotension may occur due to shock or hemorrhage, but not as a result of increased ICP.
Choice D Reason: This is a correct answer because irregular respirations are part of Cushing's Triad, which reflects impaired respiratory control due to brainstem compression from increased ICP. The respirations may be Cheyne-Stokes, central neurogenic hyperventilation, apneustic, or ataxic.
Choice E Reason: Tachycardia and bounding pulse are not signs of Cushing's Triad, which involves bradycardia and bounding pulse due to increased ICP. Tachycardia may occur due to pain, anxiety, fever, or hypoxia, but not as a result of increased ICP.
Choice F Reason: This is a correct answer because systolic hypertension with a widening pulse pressure are part of Cushing's Triad, which reflects an increased cerebral perfusion pressure due to increased ICP. The diastolic blood pressure remains stable or decreases, resulting in a widened pulse pressure.
Question 4 of 5
A blind client reports that they are having difficulty with sleep that is affecting their daytime activities. Which of the following will the nurse include in her plan of care for the client?
Correct Answer: D
Rationale: Reason: This is incorrect because a referral to a sleep study program is not the most appropriate plan of care for a blind client who has difficulty with sleep. A sleep study program is used to diagnose and treat sleep disorders such as sleep apnea, narcolepsy, or restless legs syndrome. Reason: This is incorrect because assisting the client to see if a night shift job is available is not a helpful plan of care for a blind client who has difficulty with sleep. A night shift job can disrupt the circadian rhythm and worsen the sleep quality and quantity of the client. Reason: This is incorrect because institution of opioids and sedatives is not a safe plan of care for a blind client who has difficulty with sleep. Opioids and sedatives can cause addiction, dependence, tolerance, and withdrawal symptoms. They can also impair the respiratory and cognitive functions of the client. Reason: This is the correct choice because education about non-24 disorder is an essential plan of care for a blind client who has difficulty with sleep. Non-24 disorder is a condition where the internal clock of the body does not synchronize with the 24-hour day-night cycle. It can cause irregular sleep patterns, daytime fatigue, and mood disturbances. It is more common in blind people who lack light perception. The nurse should educate the client about the causes, symptoms, and treatments of non-24 disorder.
Question 5 of 5
A nurse in an emergency department is caring for a client who has burns on the front and back of both his legs and arms. Using the rule of nines, the nurse should document burns to which percentage of the client's total body surface area (TBSA)?
Correct Answer: A
Rationale: Using the rule of nines, each arm is 9% and each leg is 18% of TBSA, with front and back equally divided. Burns on both sides of both arms (2 × 9%) and legs (2 × 18%) total 36% TBSA (
Choice
A). 54% is incorrect, as it overestimates by adding arms and legs incorrectly (
Choice
B). 27% and 18% underestimate the total burn area (
Choices C,
D). Note: The document contains an error suggesting 54%, but the correct calculation, as explained, is 36%.
