A 20-year-old female attending college is found unconscious in her dorm room. She has a fever and a noticeable rash. She has just been admitted to the hospital. Which of the following tests is most likely to be performed first?
- A. Blood sugar check
- B. CT scan
- C. Blood cultures
- D. Arterial blood gases
Correct Answer: C
Rationale: The most likely test to be performed first in this scenario is blood cultures. Blood cultures are crucial to investigate the fever and rash symptoms in an unconscious patient. This test is used to detect foreign invaders like bacteria, yeast, and other microorganisms in the blood, which could indicate a blood infection (bacteremia). A positive blood culture result confirms the presence of bacteria in the blood. A blood sugar check (choice A) may be important but is less likely to be the first test in this context. A CT scan (choice B) and arterial blood gases (choice D) are generally not the initial tests performed to investigate a fever and rash with altered mental status.

A child is seen in the emergency department for scarlet fever. Which of the following descriptions of scarlet fever is not correct?
- A. Scarlet fever is caused by infection with group A Streptococcus bacteria.
- B. "Strawberry tongue"? is a characteristic sign.
- C. Petechiae occur on the soft palate.
- D. The pharynx is red and swollen.
Correct Answer: C
Rationale: Petechiae on the soft palate are not a typical finding in scarlet fever. Scarlet fever is caused by group A Streptococcus bacteria, often presenting with a strawberry tongue, red and swollen pharynx, and a sandpaper-like rash. The presence of petechiae on the soft palate is more commonly associated with conditions like rubella rather than scarlet fever. Therefore, this description is not correct in the context of scarlet fever.
The client is seven (7) days post total hip replacement. Which statement by the client requires the nurse's immediate attention?
- A. I have bad muscle spasms in my lower leg of the affected extremity.
- B. I just can't 'catch my breath' over the past few minutes and I think I am in grave danger.
- C. I have to use the bedpan to pass my water at least every 1 to 2 hours.
- D. It seems that the pain medication is not working as well today.
Correct Answer: B
Rationale: While all statements by the client require attention, the most critical one that demands immediate action is option B. Clients who have undergone hip or knee surgery are at an increased risk of postoperative pulmonary embolism. Sudden dyspnea and tachycardia are hallmark signs of this condition. Without appropriate prophylaxis such as anticoagulant therapy, deep vein thrombosis (DVT) can develop within 7 to 14 days after surgery, potentially leading to pulmonary embolism. It is crucial for the nurse to recognize signs of DVT, which include pain, tenderness, skin discoloration, swelling, or tightness in the affected leg. Signs of pulmonary embolism include sudden onset dyspnea, tachycardia, confusion, and pleuritic chest pain. Option B indicates a potentially life-threatening situation that requires immediate intervention to prevent serious complications.
A patient with a history of diabetes mellitus is on the second postoperative day following cholecystectomy. She has complained of nausea and isn't able to eat solid foods. The nurse enters the room to find the patient confused and shaky. Which of the following is the most likely explanation for the patient's symptoms?
- A. Anesthesia reaction
- B. Hyperglycemia
- C. Hypoglycemia
- D. Diabetic ketoacidosis
Correct Answer: C
Rationale: In a postoperative diabetic patient who is unable to eat solid foods, the likely cause of symptoms such as confusion and shakiness is hypoglycemia. Confusion and shakiness are common manifestations of hypoglycemia. Insufficient glucose supply to the brain (neuroglycopenia) can lead to confusion, difficulty with concentration, irritability, hallucinations, focal impairments like hemiplegia, and, in severe cases, coma and death. Anesthesia reaction (Choice A) is less likely in this scenario as the patient is already on the second postoperative day. Hyperglycemia (Choice B) is unlikely given the patient's symptoms and history of not eating. Diabetic ketoacidosis (Choice D) typically presents with hyperglycemia, ketosis, and metabolic acidosis, which are not consistent with the patient's current symptoms of confusion and shakiness.
A patient has taken an overdose of aspirin. Which of the following should a nurse closely monitor during acute management of this patient?
- A. Onset of pulmonary edema
- B. Metabolic alkalosis
- C. Respiratory alkalosis
- D. Parkinson's disease type symptoms
Correct Answer: A
Rationale: The correct answer is to monitor the onset of pulmonary edema. In cases of aspirin overdose, metabolic acidosis is a common consequence that can lead to the development of pulmonary edema. Early signs of aspirin poisoning include symptoms like tinnitus, hyperventilation, vomiting, dehydration, and fever. Late signs may manifest as drowsiness, bizarre behavior, unsteady walking, and coma. Aspirin poisoning can cause abnormal breathing that is typically rapid and deep. Pulmonary edema may occur due to increased capillary permeability in the lungs, leading to the leakage of proteins and fluid transudation in renal and pulmonary tissues. Changes in renal tubule permeability can also affect colloid osmotic pressure, potentially contributing to pulmonary edema. Monitoring pulmonary edema is crucial in managing aspirin overdose cases to prevent further complications. Choices B, C, and D are incorrect because metabolic alkalosis, respiratory alkalosis, and Parkinson's disease type symptoms are not typically associated with aspirin overdose and are not primary concerns in its acute management.
A nurse in the emergency department is observing a 4-year-old child for signs of increased intracranial pressure after a fall from a bicycle, resulting in head trauma. Which of the following signs or symptoms would be cause for concern?
- A. Bulging anterior fontanel
- B. Repeated vomiting
- C. Signs of sleepiness at 10 PM
- D. Inability to read short words from a distance of 18 inches
Correct Answer: B
Rationale: Increased intracranial pressure after head trauma can lead to serious complications. Repeated vomiting is a concerning sign as it can indicate stimulation of the vomiting center within the brainstem due to increased pressure. This can be an early indicator of raised intracranial pressure and the need for urgent medical intervention. Bulging anterior fontanel may not be immediately apparent in a 4-year-old child and is more common in infants. Signs of sleepiness at a particular time of day are not specific to increased intracranial pressure. Inability to read short words from a distance of 18 inches may indicate vision problems but is not directly related to intracranial pressure.
