A school-age child is admitted in vaso-occlusive sickle cell crisis. The child's care should include which intervention? (Select all that apply.).
Correction of acidosis.
Adequate hydration.
Pain management.
Administration of heparin.
Replacement of factor VIII.
Correct Answer : B,C,E
Choice A rationale:
Correction of acidosis is not the primary intervention for vaso-occlusive sickle cell crisis. The crisis primarily involves pain due to the obstruction of blood flow by sickled cells. Correcting acidosis is not a direct treatment for this condition.
Choice B rationale:
Adequate hydration is essential in managing vaso-occlusive sickle cell crisis. Proper hydration helps prevent dehydration, which can worsen the crisis and lead to complications. Hydration helps maintain blood flow and prevent further sickling of red blood cells.
Choice C rationale:
Pain management is a crucial intervention for a child with vaso-occlusive sickle cell crisis. Pain results from tissue ischemia caused by sickled red blood cells. Effective pain management, often with analgesics, helps improve the child's comfort and quality of life during the crisis.
Choice D rationale:
Administration of heparin is not indicated for vaso-occlusive sickle cell crisis. Heparin is an anticoagulant that prevents blood clot formation. In sickle cell crisis, the primary issue is the obstruction of blood flow by sickled cells, not the formation of clots. Administering heparin may not address the underlying problem and can lead to potential complications.
Choice E rationale:
Replacement of factor VIII is not relevant to vaso-occlusive sickle cell crisis. Factor VIII is a protein involved in blood clotting and is primarily used in the treatment of hemophilia, a different condition unrelated to sickle cell crisis.

Correct Answer is D
Explanation
Choice A rationale: Pouring warm water over the perineum provides sensory stimulation that can trigger the micturition reflex. This is a non-invasive nursing intervention typically attempted before proceeding to more invasive measures.
Choice B rationale: Placing oil of peppermint in a bedpan is a traditional nursing measure. The aromatic vapors are thought to relax the pelvic floor muscles and urinary sphincter, facilitating spontaneous voiding.
Choice C rationale: Analgesics may reduce perineal pain that inhibits voiding, but they do not directly address a full bladder. Medications are generally not the "last resort" for immediate mechanical emptying of the bladder.
Choice D rationale: Urinary catheterization is an invasive procedure that carries a risk of infection. It is reserved as the final intervention when all non-invasive methods have failed to resolve bladder distention.
Correct Answer is B
Explanation
Choice A rationale:
Pulmonary stenosis is characterized by a systolic ejection murmur best heard at the upper left sternal border. It does not typically produce a continuous machinery-like murmur. Pulmonary stenosis results from narrowing at the pulmonary valve, obstructing blood flow from the right ventricle to the pulmonary artery.
Choice B rationale:
A continuous machinery-like murmur is characteristic of patent ductus arteriosus (PDA). PDA is a congenital heart defect where the ductus arteriosus, a fetal blood vessel that should close after birth, remains open, allowing continuous blood flow between the aorta and pulmonary artery. This murmur is often best heard in the left infraclavicular region.
Choice C rationale:
Ventricular septal defect (VSD) typically produces a harsh holosystolic murmur heard best at the lower left sternal border. VSD is a hole in the septum separating the ventricles, allowing blood to flow from the higher-pressure left ventricle to the lower-pressure right ventricle.
Choice D rationale:
Coarctation of the aorta causes a murmur due to increased blood flow across the aortic valve. However, this murmur is not continuous and is usually systolic and best heard in the back over the left scapula.
