Which of the following is TRUE about shock?
- A. A patient with severe shock does not always have an abnormally low blood pressure.
- B. Confusion and deteriorating mentation are indicative of hypotensive shock.
- C. Patients with compensated shock may not be able to maintain a normal blood pressure.
- D. A normal blood pressure does not imply that the patient is stable.
Correct Answer: B
Rationale: Confusion and deteriorating mentation are indeed indicative of hypotensive shock. It is important to note that a patient with hypotensive shock will likely exhibit deteriorating mental status. Choice A is incorrect because a patient in severe shock may not always have an abnormally low blood pressure, making it an unreliable indicator of shock severity. Choice C is incorrect because patients with compensated shock may present with normal blood pressure but still have inadequate tissue perfusion. Choice D is incorrect because a normal blood pressure does not guarantee the patient's stability, especially in cases of shock where tissue perfusion may be compromised despite normal blood pressure readings.

The nurse is performing a neurological assessment on a client post right cerebrovascular accident. Which finding, if observed by the nurse, would warrant immediate attention?
- A. Decrease in level of consciousness
- B. Loss of bladder control
- C. Altered sensation to stimuli
- D. Emotional lability
Correct Answer: A
Rationale: A decrease in the level of consciousness is a critical finding that would warrant immediate attention in a client post right cerebrovascular accident. This change may indicate an increase in intracranial pressure, leading to inadequate oxygenation of the brain. It could also reveal the presence of a transient ischemic attack, which may signal an impending thrombotic cerebrovascular accident. Loss of bladder control (choice B) can be managed and monitored but does not indicate an immediate threat to the client's life. Altered sensation to stimuli (choice C) can be a concerning finding but may not require immediate attention unless it affects the client's safety. Emotional lability (choice D) may be distressing for the client but does not pose an immediate risk to their health compared to a decrease in the level of consciousness.
Which individual is at greatest risk for developing hypertension?
- A. 45-year-old African-American attorney
- B. 60-year-old Asian-American shop owner
- C. 40-year-old Caucasian nurse
- D. 55-year-old Hispanic teacher
Correct Answer: A
Rationale: African-Americans have a higher risk of developing hypertension compared to other ethnic groups. They tend to develop high blood pressure at younger ages and are more sensitive to salt, which increases their risk of hypertension. Additionally, studies have shown that African-Americans may respond differently to hypertensive drugs. Therefore, the 45-year-old African-American attorney is at the greatest risk for developing hypertension. The other choices do not specify factors that put them at a higher risk for hypertension compared to African-Americans.
The nurse is providing discharge instructions to the mother of a child who had a cleft palate repair. Which statement should the nurse make to the mother?
- A. You should use an orthodontic nipple on the child's bottle.
- B. You need to use a plastic spoon to feed the child.
- C. You can allow the child to use a pacifier but only for 30 minutes at a time.
- D. You need to monitor the child's temperature for signs of infection using an oral thermometer.
Correct Answer: A
Rationale: After a cleft palate repair, it is crucial to use an orthodontic nipple on the child's bottle to feed them appropriately. The mother should be instructed to give the child baby food or baby food mixed with water. It is important to avoid introducing straws, pacifiers, spoons, or fingers into the child's mouth for 7 to 10 days post-surgery to prevent complications. The use of a pacifier should be avoided for at least 2 weeks following the surgical repair to promote proper healing. Additionally, taking oral temperatures should be avoided, and alternative temperature monitoring methods should be utilized to reduce the risk of infection. Therefore, options B, C, and D are incorrect because they could potentially lead to complications or hinder the child's recovery after cleft palate repair.
While planning care for a 2-year-old hospitalized child, which situation would the nurse expect to most likely affect the behavior?
- A. Strange bed and surroundings
- B. Separation from parents
- C. Presence of other toddlers
- D. Unfamiliar toys and games
Correct Answer: B
Rationale: The correct answer is 'Separation from parents.' Separation anxiety is most evident from 6 months to 30 months of age and is the greatest stress imposed on a toddler by hospitalization. If separation is avoided, young children have a tremendous capacity to withstand other stress. The other choices, such as 'Strange bed and surroundings,' 'Presence of other toddlers,' and 'Unfamiliar toys and games,' may also have an impact on the child, but separation from parents is typically the most significant factor affecting behavior in a hospitalized 2-year-old.
What drives respiration in a patient with advanced chronic respiratory failure?
- A. Hypoxemia
- B. Hypocapnia
- C. Hypercapnia
- D. None of the above
Correct Answer: A
Rationale: In patients with advanced chronic respiratory failure, such as those with chronic obstructive pulmonary disease (COPD), the respiratory drive shifts from being primarily stimulated by high levels of carbon dioxide (hypercapnia) to being driven by low oxygen levels (hypoxemia). This shift is due to the body's adaptation to chronic respiratory acidosis and hypoxemia. As a result, hypoxemia becomes the primary stimulus for respiration in these patients. Hypocapnia, a low level of carbon dioxide, is not a common driver of respiration in patients with advanced chronic respiratory failure. Therefore, the correct answer is hypoxemia.
