You note the cardiac electrical rhythm below (see 6-second EKG strip). Which of the following would BEST describe the client's rhythm?
Sinus Bradycardia
Sinus Tachycardia
Supraventricular Tachycardia
Normal Sinus Rhythm (NSR)
The Correct Answer is C
A. Sinus Bradycardia: Sinus bradycardia is characterized by a heart rate below 60 beats per minute, which is clearly not the case in this EKG strip. The observed rate of 150 bpm is well above the bradycardic range.
B. Sinus Tachycardia: Although this is a fast rhythm (over 100 bpm), sinus tachycardia typically has visible and upright P waves preceding each QRS complex. In this strip, the P waves are not clearly visible, suggesting a non-sinus origin.
C. Supraventricular Tachycardia (SVT): SVT is a rapid, regular rhythm originating above the ventricles, often with no clearly identifiable P waves and narrow QRS complexes. The rate appears very fast and regular—typical of SVT.
D. Normal Sinus Rhythm (NSR): Normal sinus rhythm is characterized by a regular heart rate between 60 and 100 beats per minute, with normal P waves preceding each QRS. The heart rate of 150 bpm in the given strip falls outside the normal range for NSR.

Correct Answer is D
Explanation
A. A 30-year-old distraught mother holding her crying child: While the mother is distraught, her condition does not appear life-threatening. This client should be triaged to a lower priority compared to those with immediate medical needs.
B. A 65-year-old conscious male with a head laceration: A head laceration in a conscious client is concerning but not immediately life-threatening unless there are signs of more serious brain injury (e.g increased intracranial pressure). This client would be triaged as urgent, not emergent.
C. A 48-year-old with a simple fracture of the lower leg: A simple fracture is painful but does not typically threaten life or limb. This client is categorized as urgent but not emergent compared to others with more critical needs.
D. A 26-year-old male who has pale, cool, clammy skin: This client is showing signs of shock, which is a medical emergency. Pale, cool, and clammy skin suggests hypoperfusion, potentially due to hemorrhage, dehydration, or trauma. This client requires immediate intervention to restore circulation and prevent further deterioration.
Correct Answer is B
Explanation
A. "Smallpox lesions appear similar to those of the varicella zoster virus": Smallpox lesions are typically round, deep, and well-defined, whereas chickenpox lesions are more superficial and tend to appear in different stages simultaneously. The two are distinguishable.
B. "Smallpox is infectious prior to the development of the maculopapular rash": Smallpox is contagious during the incubation period and before the appearance of the rash, particularly during the early febrile phase when the virus is present in respiratory secretions.
C. "Healthcare workers should receive a yearly vaccination for smallpox": Routine vaccination for smallpox is no longer recommended for healthcare workers since smallpox was declared eradicated. The vaccine is typically administered to those at high risk of exposure in the event of an outbreak, but not annually.
D. "Smallpox is a current epidemic in third-world countries": Smallpox was declared eradicated in 1980 by the World Health Organization, and there are no current epidemics of smallpox in any country.
