A healthcare professional is reviewing a patient's chart and notices that the patient suffers from conjunctivitis. Which of the following microorganisms is related to this condition?
- A. Yersinia pestis
- B. Helicobacter pylori
- C. Vibrio cholerae
- D. Haemophilus aegyptius
Correct Answer: D
Rationale: The correct answer is Haemophilus aegyptius. Haemophilus influenzae biogroup aegyptius (Hae) is a causative agent of acute and often purulent conjunctivitis, more commonly known as pink eye. Yersinia pestis, Helicobacter pylori, and Vibrio cholerae are not associated with conjunctivitis. Yersinia pestis causes the plague, Helicobacter pylori is associated with gastric ulcers, and Vibrio cholerae causes cholera.

The home health nurse visits a male client to provide wound care and finds the client lethargic and confused. His wife states he fell down the stairs two (2) hours ago. The nurse should
- A. Place a call to the client's healthcare provider for instructions
- B. Send him to the emergency room for evaluation
- C. Reassure the client's wife that the symptoms are transient
- D. Instruct the client's wife to call the doctor if his symptoms become worse
Correct Answer: B
Rationale: In this scenario, the client is presenting with concerning symptoms of lethargy and confusion after a fall. These symptoms could indicate a serious underlying issue, such as a head injury or internal bleeding. The nurse's priority is to ensure the client receives immediate evaluation and treatment to prevent any further harm. Option B is the correct choice as it emphasizes the urgency of the situation. Choices A, C, and D are incorrect because they do not address the critical nature of the client's condition. Contacting the healthcare provider, reassuring the wife, or waiting for symptoms to worsen could delay necessary medical intervention.
A thirty-five-year-old male has been an insulin-dependent diabetic for five years and now is unable to urinate. Which of the following would you most likely suspect?
- A. Atherosclerosis
- B. Diabetic nephropathy
- C. Autonomic neuropathy
- D. Somatic neuropathy
Correct Answer: C
Rationale: In this case, the correct answer is autonomic neuropathy. Autonomic neuropathy affects the autonomic nerves, which control various bodily functions including the bladder. In diabetes, it can lead to bladder paralysis, resulting in symptoms like urgency to urinate and difficulty initiating urination. Atherosclerosis (choice A) is a condition involving the hardening and narrowing of arteries, not directly related to the inability to urinate in this context. Diabetic nephropathy (choice B) primarily affects the kidneys, leading to kidney damage, but does not typically cause urinary retention. Somatic neuropathy (choice D) involves damage to sensory nerves, not the autonomic nerves responsible for bladder control, making it less likely to be the cause of the urinary issue described in the question.
During shift change, a healthcare professional is reviewing a patient's medication. Which of the following medications would be contraindicated if the patient were pregnant?
- A. Warfarin (Coumadin)
- B. Celecoxib (Celebrex)
- C. Clonidine (Catapres)
- D. Transdermal nicotine (Habitrol)
Correct Answer: A
Rationale: Warfarin (Coumadin) is contraindicated in pregnancy due to its pregnancy category X classification. It is associated with central nervous system defects, spontaneous abortion, stillbirth, prematurity, hemorrhage, and ocular defects when administered at any time during pregnancy. Fetal warfarin syndrome can occur when given during the first trimester. Celecoxib (Celebrex) is a pregnancy category C medication, which means there may be risks but benefits may outweigh them. Clonidine (Catapres) is also a pregnancy category C drug, and while animal studies have shown adverse effects on the fetus, there are limited human studies. Transdermal nicotine (Habitrol) is classified as a pregnancy category D drug, indicating positive evidence of fetal risk, but benefits may still warrant its use in pregnant women with serious conditions.
A patient's chart indicates a history of hyperkalemia. Which of the following would you not expect to see with this patient if this condition were acute?
- A. Decreased HR
- B. Paresthesias
- C. Muscle weakness of the extremities
- D. Migraines
Correct Answer: D
Rationale: The correct answer is 'Migraines.' Migraines are not a symptom typically associated with hyperkalemia. In acute hyperkalemia, one would not expect to see migraines. Symptoms of hyperkalemia often include muscle weakness, paresthesias, and cardiac manifestations such as bradycardia or even cardiac arrest. Therefore, choices A, B, and C are more commonly associated with acute hyperkalemia compared to migraines, making it the correct choice.
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.
