Correct Answer: C

Rationale: The correct answer is C. A rapid weight loss of 2 kg in 24 hours suggests significant fluid loss, which is concerning in clients on diuretics like furosemide. Increased urine output (choice A) is an expected effect of diuretic therapy. Decreased appetite (choice B) is a common side effect but not as concerning as rapid weight loss. Blood pressure of 140/90 mm Hg (choice D) is slightly elevated but not the most concerning finding in a client being treated for congestive heart failure with furosemide.

Correct Answer: B

Rationale: Corrected Rationale: Assessing cardiac status is crucial in hyperkalemia as high potassium levels can result in life-threatening arrhythmias. Monitoring the heart rhythm and ECG findings is essential to prevent cardiac complications. Neurological status, respiratory status, and gastrointestinal status are important assessments too, but in the context of hyperkalemia, cardiac status takes precedence due to the immediate risk of cardiac arrhythmias.

Correct Answer: C

Rationale: Checking the client's gag reflex before eating or drinking is the highest priority for a client at risk for aspiration pneumonia. Aspiration pneumonia can occur when food, liquids, or saliva are inhaled into the lungs, leading to inflammation or infection. Checking the gag reflex helps prevent the aspiration of substances into the lungs. Assessing the client's level of consciousness (Choice A) is important but not as immediately critical as checking the gag reflex. Monitoring oxygen saturation (Choice B) is essential for respiratory assessment but does not directly prevent aspiration. Monitoring intake and output (Choice D) is important for overall client management but does not specifically address the risk of aspiration pneumonia.

Correct Answer: C

Rationale: Activated PTT is the correct lab value to monitor for clients on heparin therapy. Activated PTT (partial thromboplastin time) helps assess the effectiveness of heparin therapy by measuring the time it takes for blood to clot. Monitoring activated PTT ensures that the client is within the therapeutic range of heparin to prevent both clotting and bleeding complications. Bleeding time (Choice A) and platelet count (Choice B) are not specific indicators of heparin therapy effectiveness. Clotting time (Choice D) is not as sensitive as activated PTT in monitoring heparin therapy.

Correct Answer: D

Rationale: When introducing solid foods to infants, iron-fortified cereal is usually recommended as the first food due to its high nutritional value and the importance of iron for the baby's development. Strained fruits (choice A) are often introduced later due to their higher sugar content. Pureed meats (choice B) and cooked egg whites (choice C) are usually introduced after iron-fortified cereal to provide additional sources of protein and other nutrients.
