Question 1 of 5
A 16-year-old female presents to the emergency room with a new complaint of chest pain. When performing a review of systems and physical examination, which of the following would substantially decrease your suspicion for a diagnosis of pulmonary embolism?
Correct Answer: C
Rationale: The correct answer is C: Rib tenderness. Rib tenderness would decrease suspicion for pulmonary embolism because it suggests a musculoskeletal origin of chest pain rather than a vascular one. Pulmonary embolism typically presents with symptoms such as shortness of breath, pleuritic chest pain, and sometimes cough, but rib tenderness is not a common finding in this condition. Fever is non-specific and can be present in various conditions, including pulmonary embolism. Shortness of breath is a key symptom of pulmonary embolism and would increase suspicion for this diagnosis.
Question 2 of 5
A nurse is assessing a dark-skinned client for pallor. What nursing assessment is best to assess for pallor in this client?
Correct Answer: A
Rationale: The correct answer is A: Assess the conjunctiva of the eye. The conjunctiva is a thin, transparent layer covering the white part of the eye. Pallor, which is paleness of the skin or mucous membranes, is more easily observed in the conjunctiva of the eye in dark-skinned individuals. This area provides a contrast to the skin tone, making it easier to detect subtle changes in color. Assessing the conjunctiva allows for a more accurate evaluation of pallor in dark-skinned clients compared to other areas like the palm, mouth, or palpation for swelling, which may not provide as clear of an indication of pallor.
Question 3 of 5
A client is having a radioisotopic imaging scan. What action by the nurse is most important?
Correct Answer: D
Rationale: The correct answer is D because educating the client about the procedure is crucial for informed consent, reducing anxiety, and promoting cooperation during the scan. This empowers the client to understand what to expect and how to prepare. Assessing for shellfish allergies (A) is not directly related to the scan. Placing the client on radiation precautions (B) is unnecessary as the exposure is minimal, and sedating the client (C) should only be considered if medically indicated, not as a routine practice.
Question 4 of 5
A patient who is suspected of having acute viral hemorrhagic fever reveals history of tick bite. Which of the following is the most possible causative agent?
Correct Answer: C
Rationale: The correct answer is C: Crimean Congo virus. This is because Crimean Congo virus is a tick-borne virus known to cause acute viral hemorrhagic fever. Tick bite history increases suspicion for this virus. A: Hantavirus is transmitted through rodent feces and urine. B: Rift Valley virus is transmitted through mosquito bites. D: Marburg virus is transmitted through contact with infected animals.
Question 5 of 5
A patient is suffered from vitamin K deficiency. Which of the coagulation factors will not be affected?
Correct Answer: C
Rationale: The correct answer is C: Factor VIII. Factor VIII is not dependent on vitamin K for its synthesis, so its levels will not be affected by vitamin K deficiency. Factor II, VII, and IX are all vitamin K-dependent factors, so their levels will decrease with vitamin K deficiency, leading to impaired blood clotting. This is due to the role of vitamin K in the post-translational modification of these factors, which is necessary for their activation. Therefore, Factor VIII is the only factor that will not be affected by vitamin K deficiency.
