A nurse in an urgent care center is assessing a client who reports a sudden onset of irregular palpitations, fatigue, and dizziness. The nurse finds a rapid and irregular heart rate with a significant pulse deficit. Which of the following dysrhythmias should the nurse expect to find on the ECG?

Sinus bradycardia

Sinus tachycardia

Atrial fibrillation

First-degree AV block

Answer and Explanation

The Correct Answer is C

Choice A Reason: This is incorrect. Sinus bradycardia is a slow and regular heart rate that originates from the sinus node. It does not cause irregular palpitations, fatigue, or dizziness, unless the heart rate is very low or the client has underlying cardiac disease.

Choice B reason: This is incorrect. Sinus tachycardia is a fast and regular heart rate that originates from the sinus node. It may cause fatigue or dizziness, but not irregular palpitations or pulse deficit.

Choice C Reason: This is correct. Atrial fibrillation is a fast and irregular heart rate that originates from multiple foci in the atria. It causes irregular palpitations, fatigue, dizziness, and pulse deficit due to ineﬀective atrial contractions and variable ventricular response.

Choice D Reason: This is incorrect. First-degree AV block is a delay in the conduction of impulses from the atria to the ventricles. It does not aﬀect the heart rate or rhythm, and does not cause any symptoms.

Correct Answer is ["A","C","D"]

Explanation

Choice A Reason: This is correct because smallpox is a highly contagious and deadly viral disease that can be used as a biological weapon. Smallpox was eradicated in 1980, but some samples of the virus are still stored in laboratories. If released intentionally, smallpox could cause a global pandemic.

Choice B Reason: This is incorrect because hydrogen cyanide is a chemical weapon of mass destruction, not a biological one. Hydrogen cyanide is a colorless gas that interferes with cellular respiration and causes rapid death.

Choice C Reason: This is correct because botulism is a serious and potentially fatal illness caused by a toxin produced by the bacterium Clostridium botulinum. Botulism can be used as a biological weapon by contaminating food or water supplies or by aerosolizing the toxin.

Choice D Reason: This is correct because anthrax is an infection caused by the spore-forming bacterium Bacillus anthracis. Anthrax can be used as a biological weapon by releasing the spores into the air or by contaminating food or water sources.

Choice E Reason: This is incorrect because sarin is a chemical weapon of mass destruction, not a biological one. Sarin is a nerve agent that blocks the transmission of nerve impulses and causes respiratory failure and death.

A. Weakened gag reﬂex B. Hyperthermia C. Absence of bowel sounds D. Paralysis E. Polyuria F. Hypotension

Correct Answer is ["A","C","D","F"]

Explanation

Choice A: A cervical spinal cord injury can impair the function of cranial nerves, leading to a weakened gag reflex and an increased risk of aspiration.

Choice B:Patients with spinal cord injuries are more likely to experience poikilothermia (difficulty regulating body temperature), but this often results in hypothermia, not hyperthermia, due to the loss of autonomic temperature control.

Choice C:Spinal shock, which often follows a spinal cord injury, can cause decreased or absent bowel sounds due to a temporary loss of autonomic function and decreased peristalsis.

Choice D:Depending on the level and severity of the injury, paralysis can occur, affecting motor function below the injury site. A cervical spinal cord injury may lead to quadriplegia (tetraplegia).

Choice E:Clients with spinal cord injuries are more likely to experience urinary retention, rather than polyuria, due to loss of bladder control and autonomic dysfunction. A foley catheter may be needed initially, followed by intermittent catheterization.

Choice F:Neurogenic shock, a potential complication of cervical spinal cord injuries, can cause hypotension due to the loss of sympathetic nervous system control over blood vessel tone, leading to vasodilation and bradycardia.
