Maintaining the infusion rate of hyperalimentation solutions is a nursing responsibility. What side effects would you anticipate from too rapid infusion rate?

Correct Answer: D

Rationale: Rationale: 1. Rapid infusion of hyperalimentation solutions can lead to circulatory overload due to increased fluid volume in the circulatory system. 2. Circulatory overload can result in symptoms such as hypertension, tachycardia, and edema. 3. Hypoglycemia can occur as a result of excess insulin release due to the sudden increase in glucose from the hyperalimentation solution. Summary: A. Cellular dehydration and potassium: Incorrect. Rapid infusion would lead to fluid overload, not dehydration. B. Hypoglycemia and hypovolemia: Incorrect. Hypovolemia is unlikely with rapid infusion, and hypoglycemia is a possible side effect. C. Potassium excess and CHF: Incorrect. Rapid infusion may cause circulatory overload, not CHF, and potassium excess is not a common side effect. D. Circulatory overload and hypoglycemia: Correct. These are the most likely side effects of rapid

Correct Answer: D

Rationale: The correct answer is D: Heart. A potassium level of 6.3 mEq/L indicates hyperkalemia, which can lead to cardiac arrhythmias and even cardiac arrest. The heart is highly sensitive to potassium levels, as it plays a crucial role in regulating the heart's electrical activity. Elevated potassium levels can disrupt this balance, leading to serious cardiac complications. Summary: A: Lungs - Not directly affected by potassium levels. B: Liver - Not directly affected by potassium levels. C: Kidneys - Kidneys regulate potassium levels but are not the most at risk for dysfunction in this scenario.

Correct Answer: C

Rationale: The correct answer is C: Amount and color of sinus drainage. Assessing the amount and color of sinus drainage is crucial in evaluating the effectiveness of nursing interventions for sinusitis discomfort as it indicates the presence of infection or inflammation. Changes in color or amount can signify improvement or worsening of the condition. WBC count (A) may indicate infection but doesn't directly reflect sinusitis discomfort. Capillary refill (B) assesses circulation, not sinusitis. Comfort level (D) is subjective and can vary among individuals, making it less reliable for assessing the effectiveness of interventions.

Correct Answer: D

Rationale: The correct answer is D: Reduce airway inflammation. Corticosteroids like methylprednisolone are used in emphysema to reduce inflammation in the airways, which can help improve lung function and symptoms. Corticosteroids work by suppressing the immune response that leads to inflammation in the airways. This can help decrease swelling, mucus production, and constriction of the airways, all of which contribute to the symptoms of emphysema. Dry secretions (choice A) and improving oxygen-carrying capacity (choice B) are not the primary purposes of corticosteroid treatment in emphysema. Treating infection that causes a low level of hemoglobin (choice C) is not relevant to corticosteroid treatment for emphysema.

Correct Answer: C

Rationale: The correct answer is C: Paroxysms or shortness of breath. Asthma is characterized by episodes of wheezing, coughing, chest tightness, and shortness of breath, known as paroxysms. This symptom is caused by inflammation and constriction of the airways in response to triggers such as allergens or irritants. A: Production of abnormally thick, sticky mucus in lungs is more indicative of conditions like cystic fibrosis, not asthma. B: Faulty transport of sodium in lung cells is associated with conditions like cystic fibrosis, not asthma. D: Altered electrolyte balance in the sweat glands is a symptom of cystic fibrosis, not asthma. In summary, paroxysms or shortness of breath is a key sign of asthma due to airway inflammation and constriction, distinguishing it from the other choices that are more indicative of cystic fibrosis.
