A nurse is examining a client who is experiencing severe dehydration. Which assessment finding should be expected?

Straw-colored urine

Taut skin

Thready pulse

Pulmonary crackles

Answer and Explanation

The Correct Answer is C

A. Straw-colored urine is a sign of adequate hydration and diluted solutes within the renal system. In severe dehydration, the nurse would expect to see dark, concentrated amber-colored urine with a high specific gravity due to the compensatory retention of water. The kidneys attempt to conserve fluid, resulting in low urine output that is highly saturated with metabolic waste products.

B. Taut skin is a clinical finding associated with fluid volume excess or edema, where the interstitial spaces are overfilled with fluid. In cases of severe dehydration, the nurse should expect poor skin turgor, where the skin remains "tented" after being pinched. Dehydration causes the skin to lose elasticity and appear loose or wrinkled as intracellular and extracellular fluid volumes are depleted.

C. A thready pulse is a classic hemodynamic manifestation of severe dehydration and hypovolemia. As the total intravascular volume decreases, the stroke volume of the heart drops, resulting in a weak, rapid, and easily obliterated peripheral pulse. This finding indicates that the patient's circulatory system is struggling to maintain adequate perfusion to the distal tissues due to the significant fluid deficit.

D. Pulmonary crackles are an assessment finding indicative of fluid accumulation in the alveoli, which is a hallmark of fluid volume excess or heart failure. Dehydration involves a lack of fluid, meaning the lungs would typically remain clear upon auscultation unless a secondary infection is present. Expecting crackles in a dehydrated patient represents a misunderstanding of the physiological differences between dehydration and overhydration.

Correct Answer is D

Explanation

A.A laparoscopic cholecystectomy is a minimally invasive procedure associated with shorter operative times and faster postoperative mobilization. While all surgeries carry some risk of VTE, the limited tissue trauma and early ambulation characteristic of this procedure result in a lower risk compared to major abdominal or thoracic surgeries. It is not the highest-risk surgery among the choices provided.

B.A subtotal thyroidectomy involves the neck area and is generally not associated with prolonged immobility or significant venous stasis in the lower extremities. The procedure is relatively localized and does not typically involve the large-scale systemic inflammation or the prolonged bed rest seen in major abdominal resections. The risk of pulmonary embolism following this surgery is clinically considered to be low.

C.An open appendectomy is a traditional abdominal surgery, but the surgical site is localized and the procedure is usually brief. While it carries more risk than a laparoscopic approach, it does not involve the extensive tissue manipulation or the prolonged recovery time seen in more complex gastrointestinal surgeries. Consequently, the risk for pulmonary embolism, although present, is not the highest in this group.

D.A total gastrectomy is a major, extensive abdominal surgery that involves significant tissue trauma and requires a prolonged period of postoperative recovery and immobility. The length of the surgery and the complexity of the resection increase the risk of venous stasis and the activation of the coagulation cascade. Patients undergoing major gastrointestinal resections are at the highest risk for developing deep vein thrombosis and subsequent pulmonary embolism.

A. High intake of red meat B. Gastrointestinal bleeding C. Current pregnancy D. Poor appetite E. Low intake of vegetables

Correct Answer is ["B","C","D"]

Explanation

A.A high intake of red meat is actually a protective factor against iron deficiency anemia because red meat is a rich source of heme iron. Heme iron has a higher bioavailability and is absorbed more efficiently by the intestinal mucosa than non-heme iron found in plant sources. Therefore, a diet high in red meat would decrease rather than increase the risk of developing a depleted iron store in the body.

B.Gastrointestinal bleeding is a primary cause of iron deficiency anemia in adults because it results in the chronic loss of hemoglobin-bound iron. Even occult blood loss from ulcers, diverticulosis, or malignancies can gradually deplete the body's iron reserves faster than they can be replenished through dietary intake. Identifying potential sites of blood loss is a critical step in diagnosing the underlying etiology of microcytic, hypochromic anemia.

C.Current pregnancy significantly increases the physiological demand for iron to support the expansion of maternal red cell mass and the development of the fetus and placenta. If dietary intake or supplementation is insufficient to meet these elevated requirements, the mother is at high risk for gestational iron deficiency anemia. This state of increased demand is a well-recognized risk factor requiring routine monitoring of hemoglobin and ferritin levels during the prenatal period.

D.A poor appetite often leads to inadequate dietary intake of essential nutrients, including iron, which is necessary for the synthesis of hemoglobin. Over time, a caloric or nutrient-restricted diet prevents the body from replacing the iron lost through normal cellular turnover and excretion. This risk factor is particularly common in geriatric populations or individuals with chronic illnesses where nutritional intake is compromised, leading to a gradual depletion of iron.

E.While some vegetables contain non-heme iron, a low intake of vegetables is not as significant a risk factor for iron deficiency as the lack of animal proteins or the presence of active bleeding. Many individuals maintain adequate iron levels through other food groups, and the iron in vegetables is less easily absorbed than that found in meat. Therefore, focusing on vegetable intake alone is not a primary diagnostic indicator for this type of anemia.
