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.

A healthcare professional is reviewing a patient's chart and notices that the patient suffers from Lyme disease. Which of the following microorganisms is related to this condition?
- A. Borrelia burgdorferi
- B. Streptococcus pyogenes
- C. Bacillus anthracis
- D. Enterococcus faecalis
Correct Answer: A
Rationale: Lyme disease, the most common vector-borne disease in the United States, is caused by the bacterium Borrelia burgdorferi. Borrelia burgdorferi is transmitted to humans through the bite of infected black-legged ticks. Streptococcus pyogenes is associated with strep throat and other infections, not Lyme disease. Bacillus anthracis causes anthrax, a separate infectious disease. Enterococcus faecalis is more commonly linked to urinary tract infections and other healthcare-associated infections, not Lyme disease.
A patient is scheduled for a magnetic resonance imaging (MRI) scan for suspected lung cancer. Which of the following is a contraindication to the study for this patient?
- A. The patient is allergic to shellfish.
- B. The patient has a pacemaker.
- C. The patient suffers from claustrophobia.
- D. The patient takes antipsychotic medication.
Correct Answer: B
Rationale: The correct answer is that the patient has a pacemaker. A pacemaker is a contraindication to MRI scanning due to the interference with the magnetic fields of the MRI scanner. This interference can potentially deactivate the pacemaker, putting the patient at risk. Patients with cardiac implantable electronic devices (CIED) are at risk for inappropriate device therapy, device heating/movement, and arrhythmia during MRI. This necessitates special precautions such as scheduling in a CIED blocked slot or having electrophysiology nurse or technician support. It is important to ensure that the patient's pacemaker is MRI conditional before proceeding with the scan. The other choices, such as being allergic to shellfish, suffering from claustrophobia, or taking antipsychotic medication, are not direct contraindications to undergoing an MRI scan for suspected lung cancer.
A patient comes to the emergency department with abdominal pain. Work-up reveals the presence of a rapidly enlarging abdominal aortic aneurysm. Which of the following actions should the nurse expect?
- A. The patient will be admitted to the medicine unit for observation and medication.
- B. The patient will be admitted to the day surgery unit for sclerotherapy.
- C. The patient will be admitted to the surgical unit and resection will be scheduled.
- D. The patient will be discharged home to follow-up with his cardiologist in 24 hours.
Correct Answer: C
Rationale: A rapidly enlarging abdominal aortic aneurysm is at significant risk of rupture, which can be life-threatening. The standard treatment for a rapidly enlarging abdominal aortic aneurysm is surgical intervention to prevent rupture. Therefore, the appropriate action for the nurse to expect is that the patient will be admitted to the surgical unit, and resection will be scheduled. Observation and medication (Choice A) are not sufficient for a rapidly enlarging aneurysm, and sclerotherapy (Choice B) is not typically used for aortic aneurysms. Discharging the patient home (Choice D) would be inappropriate and dangerous given the risk of rupture.
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 child is admitted to the hospital with a diagnosis of Wilms tumor, stage II. Which of the following statements most accurately describes this stage?
- A. The tumor is less than 3 cm in size and requires no chemotherapy.
- B. The tumor did not extend beyond the kidney and was completely resected.
- C. The tumor extended beyond the kidney but was completely resected.
- D. The tumor has spread into the abdominal cavity and cannot be resected.
Correct Answer: C
Rationale: In Wilms tumor staging, stage II indicates that the tumor extends beyond the kidney but is completely resected. This means that the tumor has spread beyond the kidney but has been successfully removed. Choices A and B are incorrect because a tumor less than 3 cm in size and a tumor that did not extend beyond the kidney do not align with the characteristics of stage II Wilms tumor. Choice D is also incorrect as it describes a more advanced stage where the tumor has spread into the abdominal cavity and cannot be completely resected. Therefore, the correct answer is C, as it accurately reflects the characteristics of a stage II Wilms tumor.
