A nurse is caring for an infant who has gastroenteritis.
Which of the following assessment findings should the nurse report to the provider?
Sunken fontanels and dry mucous membranes.
Temperature 38° C (100.4° F) and pulse rate 124/min.
Decreased appetite and irritability.
Pale and a 24-hr fluid deficit of 30 mL.
The Correct Answer is A
These are signs of severe dehydration in an infant, which can be life-threatening and should be reported to the provider immediately. The infant may need intravenous fluids and electrolytes to restore hydration and prevent complications.
Choice B is wrong because a temperature of 38° C (100.4° F) and a pulse rate of 124/min are not abnormal for an infant and do not indicate severe dehydration. These are common findings in an infant who has gastroenteritis, which is an inflammation of the stomach and intestines caused by a virus, bacteria, or parasite.
Choice C is wrong because decreased appetite and irritability are also common findings in an infant who has gastroenteritis, but they do not indicate severe dehydration. The nurse should encourage oral rehydration with fluids such as breast milk, formula, or oral electrolyte solution.
Choice D is wrong because pale skin and a 24-hr fluid deficit of 30 mL are not signs of severe dehydration in an infant.
A fluid deficit of 30 mL is less than 1 oz and is not significant for an infant who weighs about 10 kg (22 lbs). A fluid deficit of more than 10% of body weight would indicate severe dehydration.
Normal ranges for vital signs in infants are as follows:
• Temperature: 36.5° C to 37.5° C (97.7° F to 99.5° F)
• Pulse rate: 100 to 160/min
• Respiratory rate: 30 to 60/min
• Blood pressure: 65/41 to 100/50 mm Hg
Normal ranges for fluid intake and output in infants are as follows:
• Fluid intake: 100 to 150 mL/kg/day
• Fluid output: 1 to 2 mL/kg/hr

Correct Answer is A
Explanation
Warfarin is a vitamin K antagonist that inhibits the synthesis of factors II, VII, IX, and X in the liver. These factors are part of the extrinsic and common pathways of coagulation, which are measured by the prothrombin time (PT) and the international normalized ratio (INR). The INR is a standardized way of reporting the PT that accounts for the variability of different reagents and instruments. The INR is used to monitor the therapeutic effect of warfarin and to adjust the dose accordingly. The target INR range depends on the indication for warfarin, but it is usually between 2 and 3 for most conditions.
Choice B is wrong because fibrinogen level is not affected by warfarin.
Fibrinogen is a precursor of fibrin, which forms the final step of the coagulation cascade.
Fibrinogen level can be decreased in conditions such as disseminated intravascular coagulation (DIC), liver disease, or severe bleeding.
Choice C is wrong because aPTT is not affected by warfarin.
aPTT measures the intrinsic and common pathways of coagulation, which are mainly dependent on factors VIII, IX, XI, and XII.
These factors are not inhibited by warfarin.
aPTT is used to monitor the effect of heparin, a direct antithrombin agent that inhibits thrombin and factor Xa.
Choice D is wrong because platelet count is not affected by warfarin.
Platelets are cell fragments that adhere to damaged blood vessels and form aggregates to initiate hemostasis.
Platelet count can be decreased in conditions such as immune thrombocytopenia (ITP), heparin-induced thrombocytopenia (HIT), or bone marrow suppression.
Correct Answer is B
Explanation
Fish is a good source of protein and omega-3 fatty acids, which can help lower blood pressure, reduce inflammation, and prevent blood clots. Fish is also low in sodium, which is important for people with hypertension, as excess sodium can raise blood pressure by retaining fluid in the body. Fish is part of the DASH diet, which stands for Dietary Approaches to Stop Hypertension, and is a healthy eating plan that emphasizes fruits, vegetables, whole grains, low-fat dairy, nuts, seeds, legumes, and lean meats.
Choice A. Cheese is wrong because cheese is high in sodium and saturated fat, which can increase blood pressure and cholesterol levels.
Cheese should be limited or avoided by people with hypertension.
Choice C. Red meat is wrong because red meat is also high in sodium and saturated fat, as well as cholesterol, which can contribute to hypertension and heart disease.
Red meat should be eaten sparingly or replaced by leaner sources of protein like fish, poultry, or beans.
Choice D. Canned black beans are wrong because canned black beans are high in sodium, as most canned foods are preserved with salt. Canned black beans should be rinsed well before eating or replaced by dried or cooked black beans, which are lower in sodium and high in fiber, potassium, magnesium, and calcium, which are beneficial for blood pressure control.
