when a female carrier of hemophilia marries a male who is free of the disease, the risk to their off spring for each pregnancy is what:
- A. all female children will be carriers of hemophilia
- B. half the male children will have the hemophilia
- C. all male children will have the disease
- D. half the female children will have hemophilia 125
Correct Answer: B
Rationale: Hemophilia is an X-linked recessive genetic disorder, meaning it is carried on the X chromosome. Females have two X chromosomes, while males have one X and one Y chromosome. In this scenario, the female carrier has one X chromosome with the hemophilia gene and one normal X chromosome. When she has children, she has a 50% chance of passing on the X chromosome with the hemophilia gene to her sons. Therefore, half the male children will inherit hemophilia, while half will not. Daughters, on the other hand, have a 50% chance of inheriting the X chromosome with the hemophilia gene but since it is a recessive disorder, they will be carriers of hemophilia rather than having the disease itself.

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.

The physician prescribes didanosone (ddl [Videx]), 200mg PO every 12 hours, for a client with acquired immunodeficiency syndrome (AIDS) who is intolerant to zidovudine (azidothymidine ,AZT [Retrovir]). Which condition in the client's history warrants cautious of this drug?
- A. Peripheral neuropathy
- B. Hypertension
- C. Diabetes mellitus
- D. Asthma
Correct Answer: A
Rationale: Didanosine (ddl or Videx) is an antiretroviral medication used in the treatment of HIV/AIDS. However, one of the notable side effects of didanosine is peripheral neuropathy, which can manifest as tingling, numbness, or pain in the hands and feet. Since the client already has a history of peripheral neuropathy, prescribing didanosine may exacerbate this condition, making it important for the healthcare provider to exercise caution. Monitoring for any signs or symptoms of worsening peripheral neuropathy is essential in this case.
Three days after admission Ms. CC continued to have frequent stools. Her oral intake of both fluids and solids are poor. Her physician ordered parenteral hyperalimentation. Hyperalimentation solutions are:
- A. Hypotonic solutions used primarily to increase osmotic pressure of blood plasma
- B. Hypertonic solutions used primarily for hydration when hemoconcentration is present
- C. Alkalizing solutions used to treat metabolic acidosis thus reducing cellular sweating
- D. Hyperosmolar solutions used primarily to reverse negative nitrogen balance
Correct Answer: D
Rationale: Hyperalimentation solutions are hypertonic or hyperosmolar solutions used to provide complete nutrition intravenously when a patient is unable to receive adequate nutrition orally. These solutions contain a high concentration of glucose, amino acids, electrolytes, and essential vitamins and minerals. They are used to reverse negative nitrogen balance, provide adequate caloric intake, and promote healing and recovery in patients who are unable to eat or absorb nutrients properly. Hyperalimentation solutions are not used to increase the osmotic pressure of blood plasma (Choice A), for hydration when hemoconcentration is present (Choice B), or to treat metabolic acidosis (Choice C).
A client has an abnormal result on a Papanicolaou test. After admitting that she read her chart while the nurse was out of the room, the client asks what dysplasia means. Which definition should the nurse provide?
- A. Presence of completely undifferentiated tumor cells that don't resemble cells of the tissues of their origin
- B. Increase in the number of normal cells in a normal arrangement in a tissue or an organ
- C. Replacement of one type of fully differentiated cell by another in tissues where the second type normally isn't found
- D. Alteration in the size, shape, and organization of differentiated cells
Correct Answer: D
Rationale: Dysplasia refers to an alteration in the size, shape, and organization of differentiated cells. It indicates abnormal changes in the cells that can be a precursor to cancer. In the context of a Papanicolaou test, the presence of dysplasia may suggest abnormal cell growth in the cervix, which can potentially develop into cervical cancer if left untreated. It is important for the client to follow up with healthcare providers for further evaluation and management if dysplasia is detected.
