The nurse is providing discharge teaching to a client after a total hip replacement. The teaching should include instructions to:

Choice A reason:
Being free of chest pain and dyspnea is a significant indicator of successful nursing intervention in a sickle cell crisis. Chest pain and dyspnea can occur due to acute chest syndrome, a life-threatening complication of sickle cell disease characterized by vaso-occlusion in the pulmonary microcirculation. Effective pain management and oxygen therapy can alleviate these symptoms, reflecting improved respiratory function and gas exchange.

Choice B reason:
Educating the client on the importance of increasing fluid intake is crucial in managing sickle cell crisis. Adequate hydration helps to reduce blood viscosity and prevent sickling of red blood cells, which can lead to vaso-occlusive episodes. When a client verbalizes understanding and the importance of hydration, it demonstrates the effectiveness of patient education and the client's engagement in self-care.

Choice C reason:
While increasing aerobic exercises may promote endurance, it is not typically a short-term outcome measure for a sickle cell crisis. Exercise must be approached with caution in these clients, as it can increase the risk of a vaso-occlusive crisis due to dehydration and increased oxygen demand during a sickle cell crisis.

Choice D reason:
Control of acute pain to a level of 3 on a standard pain scale indicates successful pain management, a primary goal in the treatment of sickle cell crisis. Pain in sickle cell crisis is due to ischemia from obstructed blood flow by sickled cells. Effective analgesic administration and pain management strategies are essential to achieve this outcome.

Choice E reason:
A leukocyte count of 18,000/mm³ is above the normal range (4,500 to 11,000/mm³) and may indicate an infection or inflammation, which are common complications of sickle cell disease. However, this is not a direct outcome of nursing interventions aimed at managing a sickle cell crisis and thus is not a correct choice.

Choice A reason:

While polyhydramnios can be associated with congenital anomalies or fetal distress, it is not a direct indication of these conditions. Polyhydramnios refers specifically to the excessive accumulation of amniotic fluid. Congenital anomalies may lead to polyhydramnios if they affect the fetus's ability to swallow and process amniotic fluid normally, but the presence of polyhydramnios alone does not confirm these conditions.

Choice B reason:

Elevated levels of alpha-fetoprotein (AFP) in the amniotic fluid can be indicative of neural tube defects or other fetal abnormalities, but they are not a defining characteristic of polyhydramnios. Normal AFP levels in amniotic fluid at 15 to 21 weeks' gestation range from 10 to 150 ng/ml. Polyhydramnios is diagnosed based on the volume of amniotic fluid, not the AFP levels.

Choice C reason:

Carrying more than one fetus can lead to an increased amount of amniotic fluid, potentially resulting in polyhydramnios. However, the diagnosis of polyhydramnios itself does not imply a multiple gestation pregnancy. It simply indicates that there is more amniotic fluid than usual.

Choice D reason:

Polyhydramnios is defined as an excessive amount of amniotic fluid. It is typically diagnosed when the amniotic fluid index (AFI) exceeds 24 cm or the single deepest pocket (SDP) measures more than 8 cm. This condition can occur due to various reasons, including fetal anomalies, maternal diabetes, and other medical conditions.
