Nursing Elites

1. Which gland of the endocrine system secretes a hormone that assists with the sleep/wake cycle?

• A. Pituitary
• B. Pineal
• C. Pancreas
• D. Hypothalamus

Correct answer: B

Rationale: The correct answer is the Pineal gland. The Pineal gland, located in the brain, secretes melatonin, which plays a crucial role in regulating the sleep/wake cycle in response to exposure to light. The Pituitary gland (Choice A) secretes various hormones but not specifically related to the sleep/wake cycle. The Pancreas (Choice C) secretes insulin and digestive enzymes, not hormones related to the sleep/wake cycle. The Hypothalamus (Choice D) is involved in regulating many bodily functions, including hormone secretion, but it does not directly secrete the hormone that regulates the sleep/wake cycle.

2. Which type of shock is related to low blood volume?

• A. Psychogenic
• B. Cardiogenic
• C. Anaphylactic
• D. Hemorrhagic

Correct answer: D

Rationale: Hemorrhagic shock, also known as hypovolemic shock, is directly related to low blood volume due to significant blood loss. In hemorrhagic shock, the body's circulating blood volume is reduced, leading to inadequate perfusion of tissues and organs. Psychogenic shock is caused by emotional distress, not blood volume changes. Cardiogenic shock results from heart failure, not low blood volume. Anaphylactic shock is due to a severe allergic reaction, not a reduction in blood volume.

3. A patient suffering from hyperglycemia would be experiencing:

• A. Low blood sugar
• B. High blood sugar
• C. Normal blood sugar
• D. None of the above

Correct answer: B

Rationale: Hyperglycemia is a condition characterized by high blood sugar levels. In this state, there is an excess of glucose in the bloodstream. Patients with hyperglycemia are often diagnosed with diabetes. The term 'hyperglycemia' specifically refers to elevated blood sugar levels. Therefore, the correct answer is 'High blood sugar.' Choices A, C, and D are incorrect because hyperglycemia indicates elevated blood sugar levels and not low or normal levels.

4. During a heritage assessment, which question is most appropriate for the nurse to ask?

• A. "Do you smoke?"?
• B. "What is your religion?"?
• C. "Do you have a history of heart disease?"?
• D. "How many years have you lived in the United States?"?

Correct answer: D

Rationale: During a heritage assessment, it is crucial for the nurse to ask questions related to a person's country of ancestry, years in the United States, cultural practices, beliefs, and values. By asking about the number of years lived in the United States, the nurse can gain insights into the individual's cultural background and heritage. Options B, C, and A are not directly related to assessing heritage. Asking about religion only addresses one aspect of heritage, while smoking history and health history do not provide a comprehensive view of a person's heritage.

5. A 4-month-old child is at the clinic for a well-baby checkup and immunizations. Which of these actions is most appropriate when the nurse is assessing an infant's vital signs?

• A. The infant's radial pulse should be palpated, and the nurse should notice any fluctuations resulting from activity or exercise.
• B. The nurse should auscultate an apical rate for 1 minute and then assess for any normal irregularities, such as sinus dysrhythmia.
• C. The infant's blood pressure should be assessed by using a stethoscope with a large diaphragm piece to hear the soft muffled Korotkoff sounds.
• D. The infant's chest should be observed and the respiratory rate counted for 1 minute; the respiratory pattern may vary significantly.

Correct answer: B

Rationale: The nurse auscultates an apical rate, not a radial pulse, with infants and toddlers. The pulse should be counted by listening to the heart for 1 full minute to account for normal irregularities, such as sinus dysrhythmia. Children younger than 3 years of age have such small arm vessels; consequently, hearing Korotkoff sounds with a stethoscope is difficult. The nurse should use either an electronic blood pressure device that uses oscillometry or a Doppler ultrasound device to amplify the sounds. An infant's respiratory rate should be assessed by observing the infant's abdomen, not chest, because an infant's respirations are normally more diaphragmatic than thoracic. The nurse should auscultate an apical heart rate, not palpate a radial pulse, with infants and toddlers.
