Nursing Elites

1. Each small square on the EKG paper is:

• A. 0.04 seconds long and 5mm tall
• B. 0.2 seconds long and 5mm tall
• C. 0.04 seconds long and 20mm tall
• D. 0.04 seconds long and 1mm tall

Correct answer: D

Rationale: Each small square on an EKG paper represents 0.04 seconds long and 1mm tall. This standardization is essential for accurate measurements. One large square on EKG paper consists of 5 small squares in length and 5 small squares in height, which equals 0.2 seconds long and 5mm tall (0.5 mV). Choice A is incorrect because while the duration is correct, the height mentioned is not accurate. Choice B is incorrect as it provides the correct height but the duration is inaccurate. Choice C is incorrect as the height mentioned is exaggerated, and the duration is correct but the height is not. Therefore, the correct answer is 0.04 seconds long and 1mm tall.

2. What is an attack using microorganisms such as bacteria or viral agents with the intent to harm others called?

• A. Assimilation
• B. Defense intervention
• C. Bioterrorism
• D. Environmental remediation

Correct answer: C

Rationale: Bioterrorism is the act of using harmful agents like bacteria or viruses with the intention to harm others. In the context of healthcare, nurses may be involved in disaster response if bioterrorism weapons affect the community. Choice A, assimilation, refers to the process of absorbing and integrating information or ideas. Choice B, defense intervention, does not specifically relate to the intentional use of microorganisms to harm others. Choice D, environmental remediation, involves the process of cleaning up pollution or contamination in the environment, which is unrelated to the deliberate use of pathogens for harmful purposes.

3. For a patient with cirrhosis, which of the following nursing actions can the registered nurse (RN) delegate to unlicensed assistive personnel (UAP)?

• A. Assessing the patient for jaundice
• B. Providing oral hygiene after a meal
• C. Palpating the abdomen for distention
• D. Assisting the patient to choose the diet

Correct answer: B

Rationale: Providing oral hygiene after a meal is an appropriate task to delegate to unlicensed assistive personnel (UAP) as it falls within their scope of practice. UAP can assist with basic personal care activities like oral hygiene. Assessing the patient for jaundice and palpating the abdomen for distention involve making clinical assessments that require a higher level of education and training, typically performed by licensed practical/vocational nurses (LPNs/LVNs) or registered nurses (RNs). Assisting the patient to choose the diet also requires specialized knowledge and would be more appropriate for a nurse to address, considering the complexity of dietary requirements in cirrhosis.

4. When performing a physical examination, safety must be considered to protect the examiner and the patient against the spread of infection. Which of these statements describes the most appropriate action the nurse would take when performing a physical examination?

• A. Washing one's hands after removing gloves is necessary, even if the gloves are still intact
• B. Hands are washed before and after every physical patient encounter
• C. Hands are washed before the examination of each body system to prevent the spread of bacteria from one part of the body to another
• D. Gloves are worn throughout the entire examination to demonstrate concern regarding the spread of infectious diseases

Correct answer: B

Rationale: The most appropriate action for the nurse to take when performing a physical examination is to wash their hands before and after every physical patient encounter. This practice helps prevent the spread of infection. Hands should also be washed after contact with blood, body fluids, secretions, and excretions, and after contact with any equipment contaminated with body fluids. It is crucial to wash hands after removing gloves, even if the gloves appear intact. Choice A is incorrect because washing hands after removing gloves is necessary to ensure thorough hygiene. Choice C is incorrect because hands should be washed before and after every patient encounter, not just before examining each body system. Choice D is incorrect because gloves should be worn when there is potential contact with body fluids, but they do not need to be worn throughout the entire examination.

5. The nurse is taking an initial blood pressure reading on a 72-year-old patient with documented hypertension. How should the nurse proceed?

• A. Cuff should be placed on the patient's arm and inflated 30 mm Hg above the point at which the palpated pulse disappears.
• B. Cuff should be inflated to 200 mm Hg in an attempt to obtain the most accurate systolic reading.
• C. Cuff should be inflated 30 mm Hg above the patient's pulse rate.
• D. After confirming the patient's previous blood pressure readings, the cuff should be inflated 30 mm Hg above the highest systolic reading recorded.

Correct answer: C

Rationale: When measuring blood pressure, it's important to account for the possibility of an auscultatory gap, which occurs in about 5% of individuals, particularly those with hypertension due to a noncompliant arterial system. To detect an auscultatory gap, the cuff should be inflated 20 to 30 mm Hg beyond the point at which the palpated pulse disappears. This ensures an accurate measurement of blood pressure by overcoming the potential gap in sounds. Choice A is correct as it follows this guideline. Choices B and C are incorrect because inflating the cuff to 200 mm Hg or above the patient's pulse rate does not address the specific issue of an auscultatory gap. Choice D is incorrect as it focuses on the patient's previous readings rather than the current measurement technique needed to detect an auscultatory gap.
