Correct Answer: B

Rationale: Elevating the leg promotes venous return and reduces swelling, which is crucial for clients with DVT. Massaging the affected extremity can dislodge the clot and worsen the condition. Applying cold packs can cause vasoconstriction, potentially increasing the risk of clot formation. Keeping the leg dependent can impede circulation and increase the risk of clot migration.

Correct Answer: B

Rationale: Assessing parents' preferences about the amount of information is crucial because it allows for individualized care that respects their needs and emotional capacity during a stressful time. Choice A is not ideal as overwhelming parents with complete information during each encounter may not align with their preferences. Choice C, while valuable, may not always be feasible or appropriate due to privacy concerns or medical procedures. Choice D, providing brochures, may not address the specific needs or preferences of each set of parents, making it less effective than assessing individual preferences.

Correct Answer: B

Rationale: The Partial Thromboplastin Time (PTT) is the correct laboratory value to monitor heparin therapy. PTT measures the time it takes for blood to clot and is specifically used to evaluate the effectiveness of anticoagulation therapy such as heparin. Monitoring the PTT helps ensure that the heparin dose is within the therapeutic range. Platelet count, Prothrombin time (PT), and Bleeding time are not specific laboratory values for monitoring the therapeutic effect of heparin therapy. Platelet count is more indicative of platelet function, PT is used to monitor warfarin therapy, and Bleeding time assesses platelet function rather than the effect of heparin therapy.

Correct Answer: C

Rationale: Corrected Rationale: Poor problem-solving ability is a common cognitive symptom of schizophrenia. It affects the client's ability to think clearly and make decisions. Decreased level of consciousness (Choice A) is not a typical assessment finding in schizophrenia. Inability to identify common objects (Choice B) is more indicative of conditions like dementia. Preoccupation with somatic disturbances (Choice D) is characteristic of somatic symptom disorders, not schizophrenia.

Correct Answer: B

Rationale: The correct instruction the nurse should provide to a client prescribed ferrous sulfate is to take it with fluids other than coffee or tea. Coffee and tea can inhibit iron absorption. Therefore, choices A, C, and D are incorrect. Avoiding strawberries, citrus fruits, and melon is not necessary for improving absorption of ferrous sulfate, taking it on a full stomach is not recommended, and doubling the dose if a dose is missed can lead to an overdose.
