Nursing Elites

1. When printing out an EKG, a nurse notices that the QRS complexes are extremely small. What should be the next step?

• A. Alert the physician immediately as this is a sign of impending cardiac arrest.
• B. Check to see that all leads are attached and rerun the EKG.
• C. Increase the sensitivity control to 20 mm deflection.
• D. Decrease the run speed to 50.

Correct answer: C

Rationale: Increasing the sensitivity control to 20 mm deflection will double the sensitivity, allowing for better observation of the small QRS complexes. This step is crucial in obtaining a clearer EKG reading. Choice A is incorrect because small QRS complexes do not necessarily indicate impending cardiac arrest; it's more likely a technical issue. Choice B is not the first step to take when small QRS complexes are observed; it's important to adjust the settings first. Choice D is incorrect because decreasing the run speed to 50 is not the appropriate action for this situation; adjusting the sensitivity control is more relevant to improve the visualization of the complexes.

2. Which of the following safety precautions should the nurse discuss when working with an immunocompromised client?

• A. Avoid canned foods and increase consumption of fresh fruits and vegetables
• B. Hand-wash utensils after use and allow them to air dry
• C. Only drink tap water that has been filtered or boiled before consumption
• D. Never eat meals prepared in restaurants

Correct answer: C

Rationale: The correct answer is to only drink tap water that has been filtered or boiled before consumption. Immunocompromised clients are susceptible to infections, so it is essential to take precautions to prevent exposure to harmful pathogens. Drinking tap water that has been filtered or boiled helps eliminate potential pathogens that could be harmful to the client's health. Choices A, B, and D do not directly address the issue of avoiding potential pathogens that could compromise the health of an immunocompromised client. Thus, they are incorrect. Hand-washing utensils, avoiding canned foods, and increasing fruit and vegetable consumption are good general hygiene practices but may not specifically address the needs of an immunocompromised client.

3. Which of the following statements best describes substance P?

• A. Substance P decreases a client's sensitivity to pain
• B. Substance P levels are drawn before administration of narcotic analgesics
• C. Substance P is found in the brain and is responsible for pain control and management of depression
• D. Substance P is found in the dorsal horn of the spinal column

Correct answer: D

Rationale: Substance P is a neurotransmitter found in the brain and the dorsal horn of the spinal column, not just in the brain. It is associated with pain transmission and modulation. Substance P is known to cause inflammation, edema, and pain. While it plays a role in pain perception, it does not decrease a client's sensitivity to pain (Choice A), nor are its levels typically drawn before administering narcotic analgesics (Choice B). Although substance P is involved in pain control, it is not responsible for managing depression (Choice C). Therefore, the correct statement is that substance P is found in the dorsal horn of the spinal column.

4. When assessing the force or strength of a pulse, what would the nurse recall about the pulse?

• A. Is a reflection of the heart's stroke volume
• B. Typically recorded on a 0- to 3-point scale
• C. Demonstrates elasticity of the blood vessel wall
• D. Reflects the blood volume in the arteries during diastole

Correct answer: A

Rationale: When assessing the force or strength of a pulse, the nurse should recall that it is a reflection of the heart's stroke volume. The heart pumps an amount of blood (the stroke volume) into the aorta, causing arterial walls to flare and generate a pressure wave felt as the pulse in the periphery. The force of the pulse is typically recorded on a 0- to 3-point scale, not a 0- to 2-point scale. The force of the pulse does not demonstrate the elasticity of blood vessel walls or reflect the blood volume in the arteries during diastole. Therefore, choices B, C, and D are incorrect.

5. During a class on the aspects of culture, the instructor shares that culture has four basic characteristics. Which statement correctly reflects one of the characteristics of culture?

• A. Static and unchanging
• B. Members sharing similar physical characteristics
• C. Members sharing a common geographic origin and religion
• D. Adapted to specific conditions related to environmental and technical factors

Correct answer: D

Rationale: Culture has four basic characteristics, one of which is that it is adapted to specific conditions related to environmental and technical factors and to the availability of natural resources. The other three characteristics are: (1) learned from birth through the processes of language acquisition and socialization; (2) shared by all members of the cultural group; and (3) dynamic and ever-changing. Culture is not static and unchanging but is dynamic and ever-changing. Members of a culture do not necessarily share similar physical characteristics; that refers to race. Similarly, members of a culture do not necessarily share a common geographic origin and religion; that refers to ethnicity.
