Another girl was bitten by a poisonous snake. All of the following are true except
- A. The victim of a snake bite should be made to exercise the bitten extremity to hasten circulation
- B. The bite of a poisonous snake is distinguished by two fang marks
- C. Immediate severe pain and swelling distinguished the bite of a poisonous snake
- D. The tourniquet should be tight enough to prevent superficial circulation of blood thus stopping absorption of the poison
Correct Answer: A
Rationale: When it comes to snake bites, one should not exercise the bitten extremity as it can increase the spread of venom in the body. Moving the affected limb can potentially lead to the venom spreading more quickly through the lymphatic system and into the bloodstream. Therefore, it is essential to keep the victim as calm and still as possible to minimize the effects of the venom. Proper first aid for snake bites includes keeping the victim calm, immobilizing the bitten limb, and seeking immediate medical attention.
The nurse is assessing a client with multiple myeloma. The nurse should keep in mind that clients with multiple myeloma are at risk for:
- A. Chronic liver failure.
- B. Pathologic bone fractures.
- C. Acute heart failure.
- D. Hypoxemia.
Correct Answer: B
Rationale: Clients with multiple myeloma are at increased risk for pathologic bone fractures due to the disease's effects on bone tissue. Multiple myeloma is a cancer of plasma cells, a type of white blood cell found in the bone marrow. The growth of abnormal plasma cells weakens the bone structure, leading to bone lesions and an increased risk of fractures. The bone lesions can cause pain, bone deformities, and complications such as hypercalcemia. Therefore, nurses caring for clients with multiple myeloma should prioritize interventions to prevent pathologic bone fractures and manage bone health.
The nurse is preparing an adolescent for discharge after a cardiac catheterization. Which statement by the adolescent would indicate a need for further teaching?
- A. "I should avoid tub baths but may shower."
- B. "I have to stay on strict bed rest for 3 days."
- C. "I should remove the pressure dressing the day after the procedure."
- D. "I may attend school but should avoid exercise for several days."
Correct Answer: B
Rationale: The statement "I have to stay on strict bed rest for 3 days" would indicate a need for further teaching. After a cardiac catheterization, strict bed rest is usually not required for an extended period of time. The patient is typically advised to limit physical activities for a certain period but can engage in light activities as tolerated. Prolonged bed rest can increase the risk of complications such as blood clots and muscle weakness. It would be important to clarify this misconception and provide accurate information regarding post-procedure care.
To whom is RhIG (RhoGAM) administered to prevent Rh isoimmunization?
- A. Rh-negative women who deliver an Rh-positive newborn
- B. Rh-positive women who deliver an Rh-negative newborn
- C. Rh-negative newborns whose mothers are Rh positive
- D. Rh-positive fathers before conception of second newborn when first newborn was Rh positive
Correct Answer: A
Rationale: RhIG (RhoGAM) is administered to Rh-negative women who deliver an Rh-positive newborn to prevent Rh isoimmunization. Rh isoimmunization can occur when an Rh-negative mother is exposed to Rh-positive fetal blood during childbirth, leading to the production of antibodies against Rh antigen. RhIG works by binding to and destroying any fetal Rh-positive red blood cells that have entered the mother's circulation, preventing her immune system from mounting an immune response and producing antibodies. This helps to protect subsequent pregnancies from complications related to Rh isoimmunization. Therefore, RhIG administration is crucial in preventing sensitization and ensuring the health of future pregnancies in Rh-negative women who deliver an Rh-positive newborn.
A 2-month-old is diagnosed with hip dysplasia. The parent asks you how long will the child be in the hip Spica Cast. How should you respond?
- A. Not longer than 4 months.
- B. The child will be placed in a Pavlik Harness for 3 to 5 months.
- C. Following the osteotomy, the child remains in a cast for 5 months.
- D. Between 2 and 4 months.
Correct Answer: B
Rationale: Hip dysplasia in infants is often managed initially with a Pavlik Harness, which helps maintain the hips in the correct position for optimum development. The Pavlik Harness is typically worn for a period of 3 to 5 months, depending on the severity of the hip dysplasia and the response to treatment. If the dysplasia is more severe or does not respond well to the Pavlik Harness, further interventions such as hip spica casting or surgery may be required, but the initial treatment is usually with the Pavlik Harness.
