Nursing Elites

1. When is the best time for the nurse to attempt to elicit the Moro reflex during an infant examination?

• A. When the infant is sleeping
• B. At the end of the examination
• C. Before auscultation of the thorax
• D. At about the middle of the examination

Correct answer: B

Rationale: The Moro reflex, also known as the startle reflex, is best elicited at the end of the examination because it can cause the infant to cry. This reflex is triggered by a sudden change in position or loud noise, and it involves the infant's arms extending and then coming back together as if embracing. By eliciting this reflex at the end of the examination, the nurse can observe the infant's response and ensure that the examination is completed without unnecessary distress. Choices A, C, and D are incorrect because the Moro reflex is typically elicited at the end of the examination to avoid disrupting the assessment process and causing unnecessary discomfort to the infant.

2. A physician's order instructs a nurse to take a temperature at the axilla. Where would the nurse place the thermometer?

• A. In the rectum
• B. In the mouth
• C. On the temples
• D. In the armpit

Correct answer: A

Rationale: When a physician's order specifies taking a temperature at the axilla, the nurse should place the thermometer in the armpit. The axilla is the anatomical area of the armpit located under the arms, proximal to the trunk. Placing the thermometer in the rectum (Choice A) is used for rectal temperature measurements, in the mouth (Choice B) for oral temperature measurements, and on the temples (Choice C) is not a common site for temperature assessment. Therefore, the correct placement based on the given instruction is in the armpit.

3. Patients exhibiting signs of cyanosis will:

• A. show signs of hyperoxia.
• B. have increased O2 saturation.
• C. have blood levels of CO2 higher than O2 levels.
• D. None of the above.

Correct answer: C

Rationale: Cyanosis is a bluish discoloration of the skin and mucous membranes resulting from low blood oxygen levels. When a patient exhibits cyanosis, it indicates that their blood is poorly oxygenated, leading to a higher concentration of CO2 compared to oxygen. Options A and B are incorrect as cyanosis is associated with low oxygen levels, not hyperoxia or increased O2 saturation. Therefore, the correct answer is that patients exhibiting cyanosis will have blood levels of CO2 higher than O2 levels.

4. 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.

5. The healthcare professional notices that a colleague is preparing to check the blood pressure of a patient who is obese by using a standard-sized blood pressure cuff. How would this likely affect the blood pressure reading?

• A. Yield a falsely low blood pressure
• B. Yield a falsely high blood pressure
• C. Be the same, regardless of cuff size
• D. Vary as a result of the technique of the person performing the assessment

Correct answer: B

Rationale: Using a cuff that is too narrow for an obese patient would likely yield a falsely high blood pressure reading. This occurs because the standard cuff is too small for the arm's circumference, requiring more pressure to compress the artery. A tight cuff can lead to inaccurate and elevated blood pressure readings. Choices A, C, and D are incorrect because using an improperly sized cuff would not yield a falsely low blood pressure, the blood pressure reading does vary with cuff size, and the technique of the person performing the assessment is not the primary factor affecting the reading in this situation.
