Nursing Elites

1. A client has generalized petechiae and ecchymoses. The nurse should expect a prescription for which of the following laboratory tests?

• A. Platelet count
• B. Potassium level
• C. Creatinine clearance
• D. Prealbumin

Correct answer: A

Rationale: Generalized petechiae and ecchymoses can indicate a potential issue with platelet function or count. Therefore, the most relevant laboratory test to evaluate this condition would be a platelet count. Platelet count helps assess the number of platelets in the blood, which are crucial for clotting and preventing bleeding. Monitoring platelet levels can provide important information about a client's bleeding risk and overall hematologic health.

2. A patient is kept off food and fluids for 10 hours before surgery. His oral temperature at 8 a.m. is 99.8°F (37.7°C). This temperature reading probably indicates:

• A. Infection
• B. Hypothermia
• C. Anxiety
• D. Dehydration

Correct answer: D

Rationale: A patient being kept off food and fluids before surgery can lead to dehydration. Dehydration can cause a slight increase in body temperature, which could explain the elevated oral temperature reading of 99.8°F (37.7°C) in this scenario. Infections are more likely to cause higher fevers, hypothermia would present with a lower temperature, and anxiety typically does not directly affect body temperature in this manner.

3. Palpating the midclavicular line is the correct technique for assessing

• A. Baseline vital signs
• B. Systolic blood pressure
• C. Respiratory rate
• D. Apical pulse

Correct answer: D

Rationale: Palpating the midclavicular line is the correct technique for assessing the apical pulse. The apical pulse is located at the point of maximal impulse (PMI), which is typically at the fifth intercostal space at the midclavicular line. This technique allows healthcare providers to accurately assess the heart rate and rhythm by listening to the heart sounds directly at this point.

4. What is the primary purpose of handwashing?

• A. To promote hand circulation
• B. To prevent the transfer of microorganisms
• C. To avoid touching the client with a dirty hand
• D. To provide comfort

Correct answer: B

Rationale: The primary purpose of handwashing is to prevent the transfer of microorganisms. Proper hand hygiene helps reduce the risk of spreading harmful bacteria and viruses, thus promoting overall health and preventing infections. Choice A is incorrect as handwashing primarily focuses on cleanliness rather than promoting circulation. Choice C is incorrect as it implies that the main concern is avoiding client discomfort rather than preventing infection. Choice D is incorrect as while handwashing can be comforting in some situations, its primary purpose is not to provide comfort but to maintain hygiene.

5. What is the term for the body's ability to defend itself against specific invading agents such as bacteria, toxins, viruses, and foreign bodies?

• A. Hormones
• B. Secretion
• C. Immunity
• D. Glands

Correct answer: C

Rationale: The correct answer is C: Immunity. Immunity refers to the body's ability to protect itself against specific invading agents like bacteria, toxins, viruses, and foreign bodies by recognizing and destroying them. It is a crucial defense mechanism that helps maintain health and prevent infections and diseases. Choices A, B, and D are incorrect because hormones are chemical messengers, secretion is the process of releasing substances, and glands are organs that produce and release substances, none of which specifically relate to the body's defense against invading agents.
