The nurse recognizes that which statement regarding sleep is true?
Research shows that people in general get more than enough sleep.
Teenagers have a natural tendency to wake up earlier.
Sleep needs remain constant over the course of a person's lifetime.
Older adults experience a progressive decrease in deep sleep.
The Correct Answer is D
D. As individuals age, there is a natural decline in the amount of deep sleep (slow-wave sleep or Stage N3 sleep) they experience. Older adults tend to spend less time in deep sleep and may experience more fragmented sleep patterns, with more frequent awakenings during the night. This reduction in deep sleep is a normal part of the aging process and is associated with changes in sleep architecture and physiology.
A. Research indicates that a significant portion of the population does not get enough sleep, with many adults experiencing sleep deprivation due to various factors such as lifestyle, work schedules, and sleep disorders.
B. Teenagers often have a natural tendency to stay up later and have difficulty waking up early due to changes in their circadian rhythm during adolescence. This shift in sleep patterns, known as delayed sleep phase syndrome, can result in later bedtimes and waking times for teenagers.
C. Sleep needs typically change over the course of a person's lifetime. Infants and young children require more sleep than adults, with sleep duration gradually decreasing as individuals age.
Additionally, factors such as lifestyle, health status, and environmental influences can affect sleep needs at different stages of life.

Correct Answer is B
Explanation
B. Tachycardia (elevated heart rate) can be a sign of various underlying conditions, including pain, anxiety, or cardiovascular compromise. While tachycardia may occur as a response to stress or pain associated with the catheter insertion procedure, it can also indicate complications such as hemorrhage, cardiac dysrhythmias, or pulmonary embolism, which require prompt evaluation and intervention.
A. While this can be concerning, it is not typically directly related to complications of a subclavian central venous catheter insertion unless there is evidence of arterial injury or thrombosis.
C. Bibasilar crackles are abnormal lung sounds that can indicate fluid accumulation in the lungs, such as pulmonary edema or pneumonia. However, this may not be directly related to the subclavian central venous catheter insertion itself.
D. Headache is a non-specific symptom that can have numerous causes, including stress, dehydration, or tension.
Correct Answer is A
Explanation
A. In respiratory alkalosis, the pH is elevated (alkalotic), the PaCO2 (partial pressure of carbon dioxide) is decreased (hypocapnia), and the HCO3 (bicarbonate) level may be within normal limits or slightly decreased due to compensatory mechanisms. In this option, the pH is elevated (7.54), the PaCO2 is decreased (25), and the HCO3 level is within normal limits (24). These findings support respiratory alkalosis.
B. pH 7.50, PaCO2 40, HCO3 28: In this option, the pH is elevated (7.50), the PaCO2 is within normal limits (40), and the HCO3 level is elevated (28). These findings are not consistent with respiratory alkalosis. Instead, they suggest metabolic alkalosis, where both the pH and bicarbonate levels are elevated.
C. pH 7.35, PaCO2 35, HCO3 22: In this option, the pH is within normal limits (7.35), the PaCO2 is within normal limits (35), and the HCO3 level is within normal limits (22). These findings are not consistent with respiratory alkalosis.
D. pH 7.32. PaCO2 48, HCO3 24: In respiratory alkalosis, the pH is elevated (alkalotic), the PaCO2 is decreased (hypocapnia), and the HCO3 level may be within normal limits or slightly decreased due to compensatory mechanisms. In this option, the pH is within normal limits (7.32), the PaCO2 is elevated (48), and the HCO3 level is within normal limits (24). These findings are not consistent with respiratory alkalosis.
