Question 1 of 5
A client begins a regimen of chemotherapy. Her platelet count falls to 98,000. Which action is least likely to increase the risk of hemorrhage?
Correct Answer: C
Rationale: The correct answer is to implement reverse isolation. Reverse isolation is a protective measure used to protect patients from infections, not to affect the risk of hemorrhage. Testing all excreta for occult blood (Choice A) is important to monitor for signs of internal bleeding. Using a soft toothbrush or foam cleaner for oral hygiene (Choice B) is recommended to prevent gum bleeding. Avoiding IM injections (Choice D) is crucial to reduce the risk of bleeding in a client with a low platelet count. Therefore, among the given options, implementing reverse isolation is the least likely to increase the risk of hemorrhage.
Question 2 of 5
Signs of impaired breathing in infants and children include all of the following except:
Correct Answer: D
Rationale: Signs of impaired breathing in infants and children typically include nasal flaring, grunting, and seesaw breathing. Nasal flaring is the widening of the nostrils during breathing to help with air intake, grunting is a sound made during expiration to keep the airway open, and seesaw breathing is an abnormal pattern where the chest moves in while the abdomen moves out. Quivering lips are not a typical sign of impaired breathing in infants and children, making it the correct answer. Nasal flaring, grunting, and seesaw breathing are all signs indicating the need for immediate medical attention due to potential respiratory distress.
Question 3 of 5
A client has chronic respiratory acidosis caused by end-stage chronic obstructive pulmonary disease (COPD). Oxygen is delivered at 1 L/min via nasal cannula. The nurse teaches the family that the reason for this is to avoid respiratory depression, based on which of the following explanations?
Correct Answer: A
Rationale: In clients with COPD and chronic respiratory acidosis, they are compensating for low oxygen and high carbon dioxide levels. Hypoxia acts as the main stimulus to breathe in individuals with chronic hypercapnia. When oxygen is administered, it can decrease the respiratory drive by eliminating the hypoxic drive and reducing the stimulus to breathe. Therefore, delivering oxygen at 1 L/min via nasal cannula helps prevent respiratory depression by maintaining the hypoxic drive to breathe. The other options are incorrect: COPD clients do not depend on a low carbon dioxide level as they are chronically hypercapnic, they do not retain hydrogen ions with high oxygen doses, and they do not thrive on a high oxygen level.
Question 4 of 5
A nurse is caring for a client with an elevated cortisol level. The nurse can expect the client to exhibit symptoms of:
Correct Answer: C
Rationale: Elevated cortisol levels can lead to sodium and fluid retention and potassium deficit, resulting in urinary deficit. This imbalance in electrolytes and fluid can cause a decrease in urinary output. Choices B, hyperpituitarism, and D, hyperthyroidism, are incorrect as they do not directly relate to the symptoms expected with elevated cortisol levels. Option A, urinary excess, is also incorrect as high cortisol levels typically lead to fluid retention and urinary deficit, not excess.
Question 5 of 5
The anemias most often associated with pregnancy are:
Correct Answer: B
Rationale: Folic acid and iron deficiency anemia are the most common types of anemia associated with pregnancy. Approximately 50% of pregnant women experience this type of anemia. Iron deficiency anemia during pregnancy typically results from the increased plasma volume, rather than a decrease in iron levels. Moreover, if a woman has iron deficiency anemia before pregnancy, it often worsens during pregnancy. Folic acid deficiency is also prevalent during pregnancy due to the increased demand for this nutrient to support fetal development. Thalassemia and B12 deficiency, while types of anemia, are not as commonly associated with pregnancy compared to folic acid and iron deficiency anemia, making them incorrect choices in this context.
