Which is descriptive of central nervous system stimulants?
- A. They produce strong physical dependence.
- B. They can result in strong psychological dependence.
- C. Withdrawal symptoms are life threatening.
- D. Acute intoxication can lead to coma.
Correct Answer: B
Rationale: Central nervous system (CNS) stimulants, such as amphetamines and cocaine, are known to produce strong psychological dependence in individuals who use them. These substances can create a powerful craving for their effects due to their ability to increase alertness, attention, and euphoria. Psychological dependence can lead to compulsive drug-seeking behavior, even in the absence of physical withdrawal symptoms. It is important to note that while CNS stimulants can lead to physical dependence, it is typically not as pronounced as the psychological dependence that can develop.

A nurse approaches a hospitalized poststroke patient from the patient's left side to do an assessment. The patient is staring straight ahead, and does not respond to the nurse's presence or voice. Which action should the nurse take first?
- A. Walk to the other side of the bed and try again
- B. Speak more loudly and clearly
- C. Wave his or her fingers in front of the patient's face
- D. Use a picture to explain to the patient what the nurse is going to do.
Correct Answer: A
Rationale: The nurse should walk to the other side of the bed and approach the patient from the right side. Poststroke patients may have neglect syndrome, which can cause them to ignore stimuli on one side of their body. By approaching from the neglected side (the right side in this case), the nurse may be able to better capture the patient's attention and engage them in the assessment process. It is essential to adapt care to accommodate the patient's condition and ensure effective communication and interaction.
Morphine is given in acute pulmonary edema to redistribute the pulmonary circulation to the periphery by decreasing:
- A. Periphery resistance
- B. Pulmonary capillary pressure
- C. Transudation of fluid
- D. All of the above CARING FOR CLIENTS WITH HEART FAILURE
Correct Answer: B
Rationale: Morphine is given in acute pulmonary edema to decrease pulmonary capillary pressure. By reducing pulmonary capillary pressure, morphine helps to redistribute the pulmonary circulation to the periphery, leading to improved oxygenation and decreased symptoms of pulmonary edema. Morphine works to vasodilate the blood vessels, which ultimately helps decrease the pressure in the pulmonary capillaries, allowing for improved blood flow to the periphery of the lungs. This redistribution of pulmonary circulation helps to alleviate the congestion and fluid buildup in the lungs that occurs in acute pulmonary edema.
In assessing a post mastectomy client, the nurse determines that the client is in denial. The nurse can best respond by:
- A. Accepting the denial.
- B. Supporting the denial.
- C. Confronting the denial.
- D. Interpreting the denial.
Correct Answer: C
Rationale: Confronting the denial is the best response in this situation. Denial is a common defense mechanism that individuals may use when faced with overwhelming emotions or situations, such as in the case of a post-mastectomy client. By confronting the denial in a supportive and empathetic manner, the nurse can help the client acknowledge and accept their feelings, which is an important step in the healing and coping process. Ignoring or supporting the denial may hinder the client's ability to address their emotions and work through them effectively. Confronting the denial allows for open communication and helps the client move towards acceptance and adjustment.
Cow's milk allergy (CMA) is diagnosed in a 6-month-old infant. Which should the nurse recommend as a substitute formula?
- A. Nutramigen
- B. Goat's milk
- C. Similac
- D. Enfamil
Correct Answer: A
Rationale: Nutramigen is a hypoallergenic formula specifically designed for infants with cow's milk allergy (CMA). It is extensively hydrolyzed, which means the cow's milk proteins are broken down into smaller pieces, making it easier for babies with CMA to digest without triggering an allergic reaction. Other options such as goat's milk, Similac, and Enfamil are not suitable substitutes for an infant with CMA as they may still contain proteins that can cause an allergic response in these infants. Therefore, Nutramigen is the most appropriate recommendation for a 6-month-old infant diagnosed with cow's milk allergy.
Which medication is most likely included in post-operative care of a child with repair of bladder exstrophy?
