Nursing Elites

1. 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.

2. While performing CPR, a healthcare provider encounters a client with a large amount of thick chest hair when preparing to use an automated external defibrillator (AED). What is the next appropriate action for the healthcare provider?

• A. Apply the pads to the chest and provide a shock
• B. Wipe the client's chest down with a towel before applying the pads
• C. Shave the client's chest to remove the hair
• D. Do not use the AED

Correct answer: C

Rationale: When using an AED, it is crucial for the pads to have good contact with the skin to effectively deliver an electrical shock. While AED pads can adhere to a client's chest even with some hair, thick chest hair can hinder proper current conduction. In such cases, it is recommended to shave the area of the chest where the pads will be applied. Most AED kits include a razor for this purpose. The healthcare provider should act promptly to minimize delays in defibrillation. Option A is incorrect because it may lead to ineffective treatment due to poor pad adherence. Option B is not the best course of action as wiping the chest may not resolve the issue of poor pad contact. Option D is incorrect as not using the AED could jeopardize the client's chance of survival in a cardiac emergency.

3. A 70-year-old man has a blood pressure of 150/90 mm Hg in a lying position, 130/80 mm Hg in a sitting position, and 100/60 mm Hg in a standing position. How should the nurse evaluate these findings?

• A. These readings are a normal response and attributable to changes in the patient's position.
• B. The change in blood pressure readings is called orthostatic hypotension.
• C. The blood pressure reading in the lying position is within normal limits.
• D. The change in blood pressure readings is considered within normal limits for the patient's age.

Correct answer: B

Rationale: The correct answer is, 'The change in blood pressure readings is called orthostatic hypotension.' Orthostatic hypotension is defined as a drop in systolic pressure of ³20 mm Hg or ³10 mm Hg drop in diastolic pressure that occurs with a quick change to a standing position. This condition is common in individuals on prolonged bed rest, older adults, those with hypovolemia, or taking specific medications. The blood pressure readings provided in the question (150/90 mm Hg lying, 130/80 mm Hg sitting, and 100/60 mm Hg standing) demonstrate a significant change in blood pressure with position changes, which is indicative of orthostatic hypotension. Choices A, C, and D are incorrect because the readings do not indicate a normal response or blood pressure within normal limits for the patient's age; rather, they suggest the presence of orthostatic hypotension.

4. While percussing over the liver of a patient, the nurse notices a dull sound. What should the nurse do?

• A. Consider this a normal finding
• B. Palpate this area for an underlying mass
• C. Reposition the hands and attempt to percuss in this area again
• D. Consider this finding as abnormal and refer the patient for additional treatment

Correct answer: A

Rationale: When percussing over relatively dense organs, such as the liver or spleen, a dull sound is a normal finding due to the organ's density. This occurs because the sound waves produced by tapping on the organ travel through the dense tissue, resulting in a dull sound. Therefore, the correct action for the nurse in this scenario is to consider a dull sound over the liver as a normal finding. Palpating for an underlying mass (Choice B) is not indicated based on the percussion finding alone. Repositioning the hands and repeating the percussion (Choice C) may not change the dull sound over the liver. Referring the patient for additional treatment (Choice D) without understanding the normal percussion findings over the liver would be premature. Thus, the most appropriate action is to interpret the dull sound as a normal finding.

5. A child is admitted to the hospital several days after stepping on a sharp object that punctured her athletic shoe and entered the flesh of her foot. The physician is concerned about osteomyelitis and has ordered parenteral antibiotics. Which of the following actions is done immediately before the antibiotic is started?

• A. The admission orders are written.
• B. A blood culture is drawn.
• C. A complete blood count with differential is drawn.
• D. The parents arrive.

Correct answer: B

Rationale: Before starting antibiotics, a blood culture should be drawn to identify the causative organism. This step is crucial as antibiotics may interfere with the identification process. Drawing a complete blood count with differential or writing admission orders are important steps in patient care but are not as critical as obtaining a blood culture to guide appropriate antibiotic therapy. The arrival of the parents is not directly related to the immediate action required before starting antibiotics in this scenario.
