Correct Answers:

Encourage fluid intake of 3-4 liters per day

Strain urine

Keep dressing dry and intact

After extracorporeal shock wave lithotripsy (ESWL), the goal is to facilitate the passage of the fragmented kidney stone pieces through the urinary tract.

The nursing plan of care will include several interventions to ensure proper recovery and prevent complications.

Encourage fluid intake of 3-4 liters per day:

To help flush out the stone fragments, it is important to encourage increased fluid intake. Drinking plenty of fluids will assist in passing the fragments and prevent further stone formation. The recommended amount is usually 3-4 liters per day, unless contraindicated (e.g., if the patient has heart failure or kidney impairment).

Strain urine: 

Straining the urine allows the nurse to collect any remaining stone fragments. This is essential for monitoring the effectiveness of ESWL and ensuring that no stone fragments are retained in the urinary tract, which could cause an obstruction or infection.

Keep dressing dry and intact:

After ESWL, there may be a surgical site or access point where a catheter or drainage tube (such as a nephrostomy tube) was used. It is essential to keep the dressing dry and intact to prevent infection and promote healing. If there is any post-procedure incision or access site, this should be monitored for any signs of infection or leakage.

Why the other options are incorrect:

Keep the patient in bed:

After ESWL, patients are typically encouraged to ambulate as tolerated. Keeping them in bed for prolonged periods is unnecessary unless there are complications like pain or bleeding. Early ambulation can help prevent complications such as deep vein thrombosis (DVT) and improve overall recovery.

Maintain nephrostomy tube:

A nephrostomy tube is not always required after ESWL. It may be used if there is significant obstruction or if there is a need for drainage. However, not all patients who undergo ESWL will have a nephrostomy tube. The presence of such a tube depends on the individual case and the treating provider’s plan.

Summary:

The plan of care after ESWL for a kidney stone typically involves encouraging high fluid intake to help flush out stone fragments, straining urine to collect any remaining pieces, and keeping the dressing dry and intact to prevent infection. Bed rest and maintenance of a nephrostomy tube are not standard requirements for all patients post-ESWL, unless specific complications are present.

Correct Answer: Low

In patients with chronic kidney disease (CKD), impaired kidney function can lead to disrupted calcium-phosphate balance.

The kidneys are responsible for regulating phosphate and calcium levels, and when kidney function declines, this regulation is impaired.

Here's why phosphate and calcium levels are linked in CKD:

Elevated Phosphate: In CKD, the kidneys are less able to excrete phosphate, which leads to elevated phosphate levels. In this case, the patient's phosphate level is 6.2 mg/dL, which is above the normal range (usually 2.5-4.5 mg/dL).

Low Calcium: When phosphate levels rise, calcium levels often decrease because phosphate binds to calcium, forming insoluble calcium phosphate complexes. This leads to hypocalcemia (low calcium), as the free (ionized) calcium in the bloodstream is reduced.

Additionally, the impaired kidneys in CKD also produce less active vitamin D, which is necessary for calcium absorption from the intestines. This further contributes to low calcium levels.

Why the other options are incorrect:

Elevated:

Elevated phosphate levels in CKD typically lead to low calcium levels, not elevated ones, due to the binding effect of phosphate on calcium."

Normal:

The calcium level is unlikely to be normal in the presence of elevated phosphate, especially in CKD, as the two are inversely related.

Same as the phosphate level:

Calcium and phosphate levels are not typically the same in CKD. Instead, they are often inversely related (as phosphate increases, calcium decreases).

Summary:

In CKD, the kidneys' inability to properly excrete phosphate leads to elevated phosphate levels, which in turn results in low calcium levels due to the binding of phosphate to calcium. Therefore, with a phosphate level of 6.2 mg/dL, you would expect the patient's calcium level to be low.

Correct Answer: Egg yolks, beef, and legumes

Iron-rich foods are essential for patients with low iron levels, and the foods in this option contain good sources of heme iron (from animal sources like beef and egg yolks) and non-heme iron (from plant-based sources like legumes).

Beef is a rich source of heme iron, which is more easily absorbed by the body compared to non-heme iron from plant-based foods.

Egg yolks are another source of heme iron.

Legumes (like beans, lentils, and chickpeas) are high in non-heme iron, and combining them with vitamin C-rich foods can enhance absorption.

Why the other options are incorrect:

Herbal tea, apples, and watermelon:

While apples and watermelon provide some nutrients, herbal tea can inhibit iron absorption due to its tannin content. This would not be helpful for someone with low iron levels.

Sweet potatoes, artichokes, and packaged meat:

Sweet potatoes and artichokes are good sources of nutrients but are not high in iron. Packaged meat is often processed and may not be as beneficial for iron absorption as unprocessed, lean meats like beef.

Chocolate, cornbread, and cabbage:

While chocolate contains some iron, it also contains compounds like oxalates that can inhibit iron absorption. Cornbread and cabbage are not particularly high in iron, and cabbage contains compounds that can interfere with iron absorption as well.

Summary:

For someone with low iron levels, focusing on iron-rich foods like beef, egg yolks, and legumes will provide a good mix of heme and non-heme iron to help improve iron levels. Avoiding foods or beverages that inhibit iron absorption, like herbal tea, is also important.

Correct Answer: "Use of the drug could cause more bleeding."

In patients with a hemorrhagic stroke, the issue is bleeding in the brain (hemorrhage).

The use of tPA (tissue plasminogen activator), which is a clot-busting medication, is contraindicated in these patients because it works by dissolving blood clots, which could worsen the bleeding and increase the risk of further damage to the brain.

Therefore, the best response is that tPA could cause more bleeding in the case of a hemorrhagic stroke.

Why the Other Options Are Wrong:

"Please feel free to ask the neurologist":

While it's appropriate to encourage family members to ask questions, this response does not provide an explanation of why the patient did not receive tPA. The family member is seeking a specific answer, and this response is evasive and doesn't address their concern directly.

"He did not arrive within the time frame for that therapy":

While timing is crucial for administering tPA in ischemic strokes (caused by clots blocking blood flow), it is not the reason why tPA would not be used in a hemorrhagic stroke. In fact, tPA would not be administered at all to a patient with a hemorrhagic stroke due to the risk of increasing bleeding.

"Not everyone is eligible for this drug. Has he had surgery lately?":

While eligibility for tPA depends on several factors (such as time from symptom onset), the main reason for withholding tPA in a hemorrhagic stroke is the risk of worsening bleeding, not previous surgeries. This response introduces unnecessary information that is less relevant to the specific case.

Summary:

In a patient with a hemorrhagic stroke, tPA is not used because it could worsen the bleeding. The most appropriate response to the family member’s question is to explain that the use of clot-busting drugs in this case could increase the risk of further damage to the brain due to continued bleeding.

Correct Answer: Oozing blood from the IV catheter site

Disseminated Intravascular Coagulation is a condition in which the body’s clotting system is abnormally activated, leading to widespread clotting in the small blood vessels throughout the body.

This uses up clotting factors, and, as a result, bleeding can occur at various sites.

In a patient with full-thickness burns, which cause extensive tissue injury, the risk of developing DIC is increased due to the inflammatory response and release of tissue factors into the bloodstream.

Here’s why Oozing blood from the IV catheter site is the correct sign of DIC:

Oozing blood from the IV catheter site is an indication of microvascular bleeding, which is a hallmark of DIC. Since clotting factors are consumed rapidly, and fibrinogen levels may decrease, the body becomes unable to form stable clots. This results in uncontrolled bleeding from places like IV sites, surgical wounds, and mucous membranes.

Why the other options are incorrect:

Sudden onset of chest pain and frothy sputum

This is more indicative of pulmonary edema or a cardiovascular issue (e.g., myocardial infarction, heart failure). While DIC can affect the lungs and cause a pulmonary embolism or other complications, chest pain and frothy sputum are not classic signs of DIC.

Foul smelling, concentrated urine

This is more suggestive of a urinary tract infection (UTI) or dehydration, not DIC. The urine changes may be related to kidney injury, which can occur in DIC, but this alone does not point to DIC.

A reddened, inflamed central line catheter site

This suggests an infection at the catheter site, such as phlebitis or cellulitis, which is unrelated to DIC. DIC can cause widespread bleeding and clotting problems, but inflammation at a catheter site is typically due to infection or mechanical irritation, not DIC.

Summary:

Oozing blood from the IV catheter site (Option 1) is the most indicative sign of DIC in a patient with full-thickness burns. Other signs of DIC may include prolonged bleeding, organ dysfunction, and changes in laboratory values like a decrease in platelet count, fibrinogen, and an increase in D-dimer.

Correct Answer: Long-term intrathecal or epidural catheter

For patients with persistent, severe pain that has not responded to conventional approaches, more advanced pain management techniques, such as long-term intrathecal or epidural catheter placement, might be considered.

These methods involve delivering pain medication directly to the spinal cord or the epidural space, providing highly effective pain relief, especially for patients with chronic or intractable pain.

This method can deliver medication in a controlled and targeted manner, often offering more relief with lower doses and fewer systemic side effects compared to oral medications.

Why the Other Options Are Wrong:

Intravenous analgesia:

Intravenous analgesia (IV) is commonly used for acute pain or post-surgical pain management, but for persistent, severe pain that has not responded to conventional treatments, IV analgesics may not provide long-term relief or may require increasing doses, which can lead to complications such as tolerance or dependence.

Oral analgesia:

Oral analgesia (e.g., over-the-counter pain relievers or opioids) is generally the first line of treatment for pain management, but for severe, persistent pain that does not respond to conventional treatments, oral medications alone are often insufficient. This option is less likely to be effective in cases where pain has been resistant to other treatments.

Intramuscular analgesia:

Intramuscular injections are typically used for short-term, moderate pain relief and are not as effective as intrathecal or epidural methods for managing severe, persistent pain. Intramuscular injections also do not provide the same level of direct, sustained relief for chronic pain conditions.

Summary:

For patients with persistent, severe pain that is resistant to conventional approaches, long-term intrathecal or epidural catheter placement is likely to be considered as a more effective, targeted pain management strategy. This method allows for the continuous administration of pain-relieving medications directly to the area of pain, offering better control and fewer side effects compared to systemic medications.
