Clinical manifestations of Huntington's disease include:
- A. Abnormal involuntary movements (chorea)
- B. Intellectual decline
- C. Emotional disturbances
- D. All of the above
Correct Answer: D
Rationale: Huntington's disease is a progressive neurological disorder that affects movement, cognition, and behavior. The three main clinical manifestations of Huntington's disease are abnormal involuntary movements (chorea), intellectual decline, and emotional disturbances. Chorea is characterized by involuntary jerky movements that are often random and unpredictable. Intellectual decline includes difficulties with cognitive functions such as planning, organizing, and remembering. Emotional disturbances may manifest as irritability, depression, anxiety, or mood swings. Overall, individuals with Huntington's disease experience a wide range of symptoms that impact both their physical and mental well-being.

The nurse is conducting a staff in-service on renal ultrasounds. Which statement describes this diagnostic test?
- A. Computed tomography uses external radiation to visualize the renal system.
- B. Visualization of the renal system is accomplished without exposure to radiation or radioactive isotopes.
- C. Contrast medium and x-rays allow for visualization of the renal system.
- D. External radiation for x-ray films is used to visualize the renal system, before, during, and after voiding.
Correct Answer: B
Rationale: Renal ultrasound is a non-invasive imaging technique that uses high-frequency sound waves to produce images of the kidneys and surrounding structures. Unlike computed tomography (CT) scans (Choice A) or intravenous pyelograms (Choice C) which may involve exposure to radiation or contrast medium, renal ultrasounds do not expose the patient to radiation or radioactive isotopes, making it a safe option for imaging the renal system. Ultrasounds are commonly used to assess kidney size, detect kidney stones, evaluate blood flow to the kidneys, and diagnose various renal conditions, such as hydronephrosis or renal cysts.
The nurse administers chemotherapeutic drugs to a client with cancer. What adverse effects are most common?
- A. Painful mouth sores
- B. Nausea and vomiting
- C. Frequent diarrhea
- D. Constipation
Correct Answer: B
Rationale: Nausea and vomiting are common adverse effects experienced by clients undergoing chemotherapy. Chemotherapeutic drugs can irritate the lining of the digestive system, leading to these symptoms. Nausea and vomiting can significantly impact a client's quality of life and may also affect their ability to continue with treatment. Healthcare providers often prescribe anti-nausea medications to help manage these side effects and improve the client's comfort during chemotherapy treatment. It is essential for nurses to assess, monitor, and address nausea and vomiting promptly to provide optimal care for clients undergoing chemotherapy.
Niklaus was born with hypospadias; which of the following should be avoided when a child has such condition?
- A. Surgery
- B. Circumcision
- C. Intravenous pyelography (IVP)
- D. Catheterization
Correct Answer: B
Rationale: Hypospadias is a congenital condition where the opening of the urethra is located on the underside of the penis instead of the tip. If a child is born with hypospadias, circumcision should be avoided. Circumcision involves removing part of the foreskin, which can cause complications for children with hypospadias, such as affecting future surgical repair procedures or worsening the hypospadias itself. Therefore, it is recommended to avoid circumcision in children with hypospadias.
Which finding requires immediate attention in a child with glomerulonephritis?
- A. Sleeping most of the day with BP 170/90.
- B. Urine output of 190 mL in 8 hours with Coca-Cola-colored urine.
- C. Severe headache and photophobia.
- D. Refusal to eat with poor appetite.
Correct Answer: C
Rationale: A severe headache with photophobia may indicate hypertensive encephalopathy; this requires prompt evaluation.
The nurse is preparing a parent of a newborn for home phototherapy. Which statement made by the parent would indicate a need for further teaching?
- A. "I should change the baby's position many times during the day."
- B. "I can dress the baby in lightweight clothing while under phototherapy."
- C. "I should be sure that the baby's eyelids are closed before applying patches."
- D. "I can take the patches off the baby during feedings and other caregiving activities."
Correct Answer: D
Rationale: The correct statement should be that the patches need to remain on the baby's eyes at all times during phototherapy. Removing the eye patches can potentially allow harmful light exposure to the eyes, which can lead to complications such as eye damage. It is essential for the parent to understand the importance of keeping the eye patches on to protect the baby's eyes during phototherapy. Therefore, further teaching is needed to emphasize the importance of leaving the eye patches on at all times, even during feedings and caregiving activities.
