Nursing Elites

1. When performing an EKG, the patient starts to laugh out of feelings of anxiety. What would you expect the EKG to show? (Choose the BEST answer.)

• A. Increased pulse rate, normal EKG
• B. Decreased pulse rate, abnormal EKG
• C. Tachycardia, poor EKG graph
• D. Bradycardia, poor EKG graph

Correct answer: C

Rationale: When a patient laughs due to anxiety during an EKG, it is likely to cause tachycardia, which is a rapid heart rate. This increased heart rate can lead to poor EKG graph quality as the electrical signals from large moving muscles can interfere with data collection from the chest leads. Therefore, in this scenario, the EKG is expected to show tachycardia with poor graph quality. Choices A, B, and D are incorrect because a patient laughing out of anxiety is more likely to result in an increased pulse rate (tachycardia) rather than a decreased pulse rate (bradycardia) or a normal EKG.

2. The nurse is assessing children in a pediatric clinic. Which statement is true regarding the measurement of blood pressure in children?

• A. Blood pressure guidelines for children are based on age.
• B. Phase II Korotkoff sounds are the best indicator of systolic blood pressure in children.
• C. Using a Doppler device is recommended for accurate blood pressure measurements until adolescence.
• D. The disappearance of phase V Korotkoff sounds can be used for the diastolic reading in children.

Correct answer: D

Rationale: The disappearance of phase V Korotkoff sounds can be used for the diastolic reading in children, as well as in adults. Blood pressure guidelines for children are based on more than just age, but also sex and height. Phase I Korotkoff, not Phase II, is the best indicator of systolic blood pressure. The true statement regarding the measurement of blood pressure in children is that the disappearance of phase V Korotkoff sounds can be used for the diastolic reading in children, as well as in adults.

3. A client has died approximately one hour ago. The nurse notes that the client's temperature has decreased in the last hour since their death. Which of the following processes explains this phenomenon?

• A. Rigor mortis
• B. Postmortem decomposition
• C. Algor mortis
• D. Livor mortis

Correct answer: C

Rationale: Algor mortis occurs after death when the body's circulation stops, and the client's temperature begins to fall. The client's temperature will drop by approximately 1.8 degrees per hour until it reaches room temperature. During algor mortis, the client's skin gradually loses its elasticity. Rigor mortis refers to the stiffening of the body after death due to chemical changes in the muscles. Postmortem decomposition is the breakdown of tissues after death. Livor mortis is the pooling of blood in the dependent parts of the body, causing a purple-red discoloration.

4. Which bloodborne pathogen is the most virulent? (Choose the BEST answer.)

• A. HCV
• B. HPV
• C. HIV
• D. HBV

Correct answer: A

Rationale: The correct answer is HCV (Hepatitis C Virus). Hepatitis C is considered the most virulent bloodborne pathogen, being 100 times more virulent than Hepatitis B. HPV (Human Papillomavirus) is a sexually transmitted infection but is not a bloodborne pathogen. HIV (Human Immunodeficiency Virus) affects the immune system but is not as virulent as Hepatitis C in terms of bloodborne transmission. HBV (Hepatitis B Virus) is less virulent compared to HCV in the context of bloodborne transmission.

5. In the term 'Hemoglobin,' the suffix '-globin' means:

• A. Protein
• B. Iron
• C. Metal
• D. Blood

Correct answer: A

Rationale: The suffix '-globin' in the term 'Hemoglobin' specifically refers to a protein. Hemoglobin is a protein found in red blood cells that carries oxygen. Choice B, 'Iron,' is incorrect as iron is a mineral component of hemoglobin but not the meaning of the suffix. Choice C, 'Metal,' is too broad and not specific to the meaning of the suffix in this context. Choice D, 'Blood,' is incorrect as it refers to the overall term 'Hemoglobin' rather than the specific meaning of the suffix '-globin.' Therefore, the correct answer is A: 'Protein.'
