Correct Answer: C: Serum potassium level is 3.

Explanation

Option C: Serum potassium level is 3.

Digoxin toxicity is more likely to occur in the presence of hypokalemia (low potassium levels). The normal serum potassium range is 3.5 to 5.0 mEq/L, so a level of 3.0 mEq/L is low and places the client at high risk for digoxin toxicity, which can cause life-threatening arrhythmias. Common signs of digoxin toxicity include nausea, vomiting, visual disturbances (seeing halos or yellow-green vision), and cardiac dysrhythmias. The nurse should withhold the digoxin dose and notify the healthcare provider immediately.

Explanation of Incorrect Answers:

Option A: Serum digoxin level is 1.5.

The normal therapeutic range for digoxin is 0.5 to 2.0 ng/mL. A serum digoxin level of 1.5 ng/mL is within the therapeutic range and does not indicate toxicity. The nurse would not withhold the medication based on this lab value alone.

Option B: Blood pressure is 104/68.

While digoxin has some effects on lowering blood pressure, it primarily affects heart rate and contractility rather than systemic blood pressure. A blood pressure of 104/68 mmHg is within a safe range, so this is not a reason to withhold the medication.

Option D: Apical pulse is 68/min.

Digoxin slows the heart rate, so the nurse should always check the apical pulse for one full minute before administration. The usual protocol is to withhold digoxin if the apical pulse is below 60 beats per minute in adults. Since 68 beats per minute is within the normal range, the nurse should not withhold the medication based on this finding.

Summary:

The nurse should withhold digoxin in a client with hypokalemia (serum potassium of 3.0 mEq/L) because low potassium increases the risk of digoxin toxicity and dangerous arrhythmias. The other values are within normal or acceptable ranges and would not justify withholding the medication.

The correct answer is b. Tenderness upon palpation and generalized erythema.

Explanation:

b. Tenderness upon palpation and generalized erythema:

Psoralen and ultraviolet A (PUVA) therapy is used to treat psoriasis, and it involves the use of a medication (psoralen) combined with UVA light exposure. If a patient is overexposed to this treatment, they may experience erythema (redness) and tenderness similar to sunburn, which indicates an overexposure to ultraviolet light. This can cause skin damage, and it is a sign that the therapy needs to be adjusted to prevent further harm. The symptoms of erythema and tenderness are a result of the skin's reaction to excessive UV radiation.

Why the other options are incorrect:

a. Thick skin plaques topped by silvery white scales:

This is a characteristic feature of psoriasis vulgaris itself, not a sign of overexposure to PUVA. Psoriasis typically presents with thick plaques covered by silvery scales, but these symptoms are not an indication of overexposure to the treatment.

c. Brown, rough, greasy, wart-like papules on the face:

This finding is more indicative of seborrheic keratosis, which is a benign skin condition, not an indication of overexposure to PUVA therapy. Overexposure to UV light does not typically result in these types of lesions.

d. Requires sunglasses because sunlight hurts eyes:

While photosensitivity can be a side effect of PUVA therapy, requiring sunglasses because sunlight hurts the eyes would typically occur with overexposure to sunlight, not necessarily from PUVA itself. Additionally, this can be a common side effect of certain medications, but it is not a direct indicator of overexposure to the PUVA treatment.

Summary:

Tenderness upon palpation and generalized erythema is the primary sign of overexposure to PUVA treatment and requires immediate attention. The other options describe either normal signs of psoriasis or conditions unrelated to PUVA overexposure. It is important for the nurse to monitor for signs of overexposure to prevent skin damage and adjust treatment accordingly.

Correct Answer: B: Completes education and becomes self-supporting.

Explanation:

While completing education and becoming financially independent are significant life achievements, they do not universally define success in young adulthood. Many individuals take alternative paths, such as entrepreneurship, vocational training, or extended education. Additionally, success in young adulthood is more closely associated with the ability to establish meaningful relationships, develop a stable sense of identity, and adapt to adult roles. According to Erik Erikson’s psychosocial development theory, young adulthood is defined by the stage of intimacy versus isolation, where individuals seek to form close relationships and establish independence. Financial stability is important, but personal identity and relationships hold greater significance in measuring success in this life stage.

Why the Other Options Are Incorrect:

Option A: Demonstrates a conceptualization of death and dying.

Understanding death and mortality is more relevant in middle and late adulthood rather than young adulthood.

Option C: Creates a new definition of self and roles with others.

This is the best indicator of successful young adulthood, as it reflects the ability to develop meaningful relationships and adjust to new social roles.

Option D: Develops a strong need for parental support and approval.

Young adulthood is about independence. A strong reliance on parental approval may indicate difficulty transitioning into adulthood rather than success.

Summary:

While completing education and becoming self-supporting are important milestones, they do not solely define success in young adulthood. Personal growth, identity formation, and meaningful relationships are stronger indicators of developmental success in this life stage.

Correct Answer: D. Adequate cellular nourishment.

Explanation

Polyphagia, or excessive hunger, is a classic symptom of diabetes mellitus, especially when blood glucose levels are poorly controlled. It occurs because glucose cannot enter the cells due to insulin deficiency or resistance, leading to cellular starvation. The body compensates by increasing hunger in an attempt to obtain more energy. The priority outcome for a client experiencing polyphagia is ensuring adequate cellular nourishment, which is achieved by improving glucose metabolism through insulin or other glucose-lowering therapies.

Why the Other Options Are Incorrect:

A. Fluid and electrolyte balance.

Although diabetes can lead to fluid and electrolyte imbalances, especially in cases of diabetic ketoacidosis (DKA) or hyperosmolar hyperglycemic state (HHS), polyphagia itself is not directly related to dehydration or electrolyte disturbances. Instead, excessive thirst (polydipsia) and frequent urination (polyuria) are more relevant to fluid balance concerns in diabetes.

B. Prevention of water toxicity.

Water toxicity, or hyponatremia due to excessive water intake, is not typically a concern in diabetes-related polyphagia. While excessive thirst (polydipsia) may lead to excessive water intake, the kidneys usually excrete excess fluid to prevent water toxicity. This option is more relevant in conditions like syndrome of inappropriate antidiuretic hormone secretion (SIADH).

C. Reduced glucose in the urine.

Although glycosuria (glucose in the urine) is a sign of poor glucose control, it is not the primary outcome for managing polyphagia. The main goal is to improve glucose uptake by the cells so they receive adequate nourishment. Reducing urine glucose is an effect of proper diabetes management but not the primary priority when addressing polyphagia.

Summary:

Polyphagia occurs in diabetes because cells are deprived of glucose due to insufficient insulin or insulin resistance. The priority outcome is ensuring that cells receive adequate nourishment, which is best achieved through proper blood glucose control. While fluid balance, glycosuria, and water toxicity may be concerns in diabetes, they are not directly related to polyphagia. Thus, ensuring adequate cellular nourishment is the most appropriate goal.

The correct answer is C. Schedule extra rest periods.

Explanation:

Multiple sclerosis (MS) is a chronic neurological disorder that affects the central nervous system (CNS), leading to a wide range of symptoms, including paresthesias (abnormal sensations like tingling or numbness), diplopia (double vision), and nystagmus (involuntary eye movements). These symptoms often occur during an exacerbation or flare-up of the disease, which can be triggered by various factors such as heat, stress, or infection. During an exacerbation of MS symptoms, rest is a key component of the care plan. Extra rest periods can help reduce fatigue, which is a common issue for people with MS, and allow the body to better manage the inflammation or disease activity affecting the CNS.

Why the Other Options Are Incorrect:

A. Stay out of direct sunlight: While it is important for individuals with MS to avoid heat (which can worsen symptoms temporarily), there is no direct relationship between sunlight and MS exacerbations. However, overheating (such as from direct sunlight, hot showers, or exercise) can worsen symptoms, so the client should avoid overheating, but this advice does not directly address the current symptom exacerbation.

B. Restrict intake of high-protein foods: There is no specific dietary restriction related to protein intake in multiple sclerosis. While nutrition plays a role in overall health, restricting high-protein foods is not necessary for managing MS exacerbations. A well-balanced diet is generally recommended for people with MS.

D. Go to the emergency room immediately: While some MS exacerbations may require urgent medical attention, this is not necessarily the case for mild to moderate symptoms like paresthesias, diplopia, and nystagmus, which are commonly seen during flare-ups. Unless the client is experiencing severe symptoms such as loss of mobility or breathing difficulties, there is no immediate need to go to the emergency room.

Summary:

The best recommendation for a client with multiple sclerosis experiencing an exacerbation of symptoms like paresthesias, diplopia, and nystagmus is to schedule extra rest periods to help manage fatigue and facilitate recovery from the flare-up.

The correct answer is: B. Disabled family coping related to dissonant coping style of significant person.

Explanation:

In this scenario, the client's spouse is showing frustration and is taking over care activities, which reflects a dissonant coping style. This means the spouse's coping response (taking over the tasks) is not in alignment with the client's needs for independence and self-care, which can hinder the client's recovery and autonomy. The nursing diagnosis "Disabled family coping" reflects the family dynamics, specifically the impact of the spouse’s actions, and addresses how the family's coping style is affecting the situation.

Why the other options are incorrect:

A. Situational low self-esteem related to functional impairment and change in role function: Although the client may experience feelings of low self-esteem due to functional impairment and role changes, this diagnosis focuses more on the client's internal struggles, not the interaction with the family. The issue here is more about how the family is coping with the change, rather than the client's own perception of self-esteem.

C. Interrupted family processes related to shift in health status of family member: This diagnosis could be appropriate if the family was struggling with overall changes to family dynamics, but the primary issue here is the dissonant coping by the spouse, rather than a broad interruption in family processes.

D. Risk for ineffective therapeutic regimen management related to complexity of care: This diagnosis would be relevant if there were concerns about the client's ability to manage their own care or if the complexity of the regimen was overwhelming for the client. However, the issue here revolves more around the family's adaptation to the client's needs and the spouse's role, not the complexity of the care regimen itself.

Summary:

The correct diagnosis focuses on the family's disabled coping in response to the spouse’s reaction to the client's condition. This diagnosis helps address the need for support and guidance in fostering healthier coping mechanisms for both the client and the family.

Correct Answer: C. Use daily reminders to take immunosuppressants.

Explanation 

After a kidney transplant, one of the most critical components of care is preventing organ rejection and ensuring the health of the transplanted kidney. Immunosuppressant medications are prescribed to prevent the immune system from attacking the new kidney. The client must take these medications exactly as prescribed, usually for the rest of their life. Missed doses of immunosuppressants increase the risk of organ rejection and potentially the failure of the transplant. For this reason, using daily reminders (such as alarms, pillboxes, or setting up a reminder system) to ensure they take their medications consistently is of the utmost importance.

Why the Other Options Are Incorrect:

A. Weigh weekly.

While monitoring weight is important, particularly for detecting fluid retention (which could indicate kidney dysfunction or rejection), it is not as critical as ensuring the regular use of immunosuppressant medications. Weekly weight checks could be part of the post-transplant care plan but are not the most critical discharge instruction.

B. Report symptoms of secondary Candidiasis.

While secondary Candidiasis (a fungal infection) is a possible complication due to immunosuppressant therapy, it is not as immediate or important to the transplant's success as the consistent use of immunosuppressant medications. Clients should still be educated about signs of infection, but the most urgent discharge instruction is related to the medication regimen.

D. Stop cigarette smoking.

While stopping cigarette smoking is beneficial for overall health and may help improve kidney transplant outcomes over time, it is not the most immediate concern post-transplant. The most critical issue right after a kidney transplant is to ensure that the client follows their immunosuppressant regimen correctly to prevent transplant rejection.

Summary:

The most important discharge instruction after a kidney transplant is to use daily reminders to take immunosuppressants. These medications are essential in preventing organ rejection and ensuring the success of the transplant. While other instructions like monitoring weight, recognizing symptoms of infections, and stopping smoking are also important, they are secondary to ensuring medication adherence for transplant success.

The correct answer is: c. Substances that change a cell so that it becomes cancerous are potential sources of cancer.

Explanation

Carcinogens are substances or agents that can cause cancer by changing the genetic material (DNA) within cells, leading to mutations that may result in uncontrolled cell growth. These changes can trigger the development of cancer. Carcinogens can be chemicals, radiation, or biological agents that directly alter the DNA in normal cells, transforming them into cancerous cells.

Why the other options are incorrect:

a. Environmental factors such as sunlight and chemicals can cause cancer to spread. This statement is partially true, but it is misleading. While sunlight and chemicals can cause cancer by inducing mutations in cells, they do not typically cause cancer to "spread." The spread of cancer (metastasis) involves the movement of cancer cells to other parts of the body, which is a process distinct from carcinogenesis (the initial formation of cancer). Carcinogens may contribute to the development of cancer but are not directly responsible for the spread.

b. Carcinogens are substances that contain cancerous cells. This is incorrect. Carcinogens do not contain cancerous cells. Instead, they are substances that have the potential to cause cancer by damaging cells' DNA or inducing mutations, which can eventually lead to cancer formation.

d. Carcinogens are in the environment and cannot be avoided. This statement is partially true, but it is overly deterministic. While carcinogens are in the environment (such as tobacco smoke, certain chemicals, and radiation), not all carcinogens are unavoidable. Many can be avoided or minimized through lifestyle changes, such as avoiding tobacco smoke, limiting alcohol consumption, wearing sunscreen, and reducing exposure to hazardous chemicals.

Summary

The correct understanding of carcinogens is that they are substances that can cause cancer by altering cell DNA, making c. Substances that change a cell so that it becomes cancerous are potential sources of cancer the correct answer.

Correct answer: C. Crohn's disease with colectomy

Explanation:

Peritoneal dialysis (PD) involves the use of the peritoneal membrane in the abdomen as a filter to remove waste products from the blood. This treatment requires that the peritoneal cavity be accessible and functional for the dialysis process. Crohn's disease is an inflammatory bowel disease that can cause chronic inflammation in the intestines, particularly the ileum and colon. Colectomy, the surgical removal of the colon, is a common treatment for severe Crohn's disease. This history presents a contraindication for peritoneal dialysis because the bowel and peritoneal cavity may be compromised by inflammation, adhesions, or scarring, which could interfere with the effectiveness and safety of the dialysis process. Additionally, peritoneal dialysis requires a functioning peritoneal cavity, and a colectomy could disrupt this cavity's ability to effectively carry out dialysis, increasing the risk of complications such as infections or inadequate dialysis.

Why the other options are wrong:

A. Type 2 Diabetes Mellitus:

While diabetes is a common comorbidity in clients with chronic kidney disease (CKD), it is not a contraindication for peritoneal dialysis. In fact, diabetes can contribute to kidney failure, and patients with diabetes who develop CKD can often undergo peritoneal dialysis if they are otherwise healthy and suitable candidates. However, diabetic patients may require closer monitoring for infections due to the increased risk associated with dialysis access sites.

B. Nephrotic syndrome history:

Nephrotic syndrome, a condition characterized by excessive protein loss in the urine, can lead to chronic kidney disease and may eventually require dialysis. Nephrotic syndrome itself does not contraindicate peritoneal dialysis. In fact, individuals with nephrotic syndrome can benefit from this treatment modality, provided there are no other contraindications.

D. Latent hepatitis C:

Latent hepatitis C refers to a chronic infection with the hepatitis C virus (HCV) that is asymptomatic. Although HCV can lead to liver damage over time, it does not preclude the use of peritoneal dialysis. In fact, hepatitis C infection is not typically a contraindication for peritoneal dialysis unless the patient has significant liver cirrhosis or liver failure. In the case of latent HCV, the patient can still undergo peritoneal dialysis, though liver function would need to be monitored.

Summary:

The history of Crohn's disease with colectomy is the most important contraindication for peritoneal dialysis because it can impair the functioning of the peritoneal cavity, making dialysis less effective and increasing the risk of complications. The other conditions—Type 2 diabetes mellitus, nephrotic syndrome, and latent hepatitis C—do not directly contraindicate peritoneal dialysis, though they may require additional management and monitoring.
