Correct Answer: B

Rationale: Hair loss postpartum is a common temporary condition caused by hormonal changes that occur after giving birth. This condition is known as postpartum alopecia and is a normal part of the postpartum period. It is important for the nurse to reassure the client that this hair loss is temporary and usually resolves on its own without the need for medical intervention. Choice A is incorrect because postpartum hair loss is primarily due to hormonal changes rather than nutritional deficiency. Choice C is incorrect as thyroid disorder is not typically the cause of postpartum hair loss. Choice D is incorrect as poor hair care during pregnancy does not cause postpartum hair loss.

Correct Answer: D

Rationale: Secretory diarrhoea is not a clinical type but a distinct mechanism of diarrhoea characterized by increased electrolyte secretion. Acute watery, bloody, and persistent diarrhoea are recognized clinical types associated with different underlying causes and pathophysiologies. Acute watery diarrhoea is common in infectious gastroenteritis, bloody diarrhoea can be caused by inflammatory conditions or infections, and persistent diarrhoea typically lasts for more than 14 days due to various reasons like infections, malabsorption, or inflammatory bowel diseases.

Correct Answer: C

Rationale: Warfarin is a medication commonly used as a blood thinner to prevent blood clot formation. It works by inhibiting the clotting factors in the blood, thereby reducing the risk of clot formation and helping in the management of conditions like congestive heart failure and arrhythmias. Choices A, B, and D are antibiotics and do not have blood-thinning properties like Warfarin.

Correct Answer: C

Rationale: Inability to lie supine is a characteristic sign of lower respiratory infection. This positioning preference is often seen in patients with lower respiratory infections due to discomfort or difficulty breathing when lying flat on their back. While cough and fever are common symptoms associated with respiratory infections, they are not specific to lower respiratory infections. Inability to eat may indicate general illness or discomfort but is not a specific indicator of lower respiratory infection.

Correct Answer: B

Rationale: Applying a warm compress to the lower abdomen can help relax the muscles and stimulate voiding in postpartum clients. It promotes vasodilation, increases blood flow to the area, and can aid in relieving urinary retention. Encouraging caffeine-free beverages can also be beneficial as caffeine can irritate the bladder and worsen the situation. Increasing fluid intake helps prevent urinary stasis and promotes bladder emptying. Kegel exercises can strengthen pelvic floor muscles over time, but in the immediate situation of difficulty voiding, a warm compress is more appropriate.
