Rationale: Lubricating the catheter tip before insertion is crucial for female urinary catheterization. This step helps reduce discomfort for the patient and facilitates smooth catheter insertion into the urethra. Using sterile technique maintains asepsis during the procedure, inserting the catheter 2-3 inches ensures proper placement, and inflating the balloon after insertion secures the catheter in place without causing trauma. Proper technique is fundamental for patient comfort, preventing infection, and ensuring the success of the catheterization procedure.

Correct Answer: C

Rationale: Increasing fiber intake is a beneficial dietary modification for clients with hypertension. Fiber helps in reducing blood pressure and improving cardiovascular health by promoting better digestion and regulating cholesterol levels. Therefore, advising a client with hypertension to increase fiber intake can be beneficial for their overall health. In contrast, increasing sodium intake can lead to higher blood pressure, reducing potassium intake is not recommended as potassium helps in regulating blood pressure, and reducing calcium intake is not typically necessary for hypertension management.

Rationale: Redness and warmth of the affected limb are classic signs of deep-vein thrombosis (DVT) due to inflammation and increased blood flow. These symptoms occur as a result of the blood clot obstructing normal blood flow and causing localized inflammation in the affected limb. Swelling of the affected limb, diminished peripheral pulses, and coolness are not typically associated with DVT. Swelling can be present but is often accompanied by the characteristic redness and warmth. Diminished pulses and coolness are more indicative of arterial insufficiency rather than venous thrombosis.
