Clinical Nursing Fundamental Exam

The correct answer is A: 3.4 mEq/L.

Explanation of the Correct Answer

The normal potassium (K⁺) range is 3.5 – 5.0 mEq/L. Since furosemide (Lasix) is a loop diuretic, it promotes the excretion of sodium, water, and potassium through the kidneys, which can lead to hypokalemia (low potassium levels).

The minimum safe potassium level before administering furosemide is typically 3.5 mEq/L.

If the potassium level is below 3.5 mEq/L, the nurse should hold the medication and notify the physician to prevent complications such as cardiac arrhythmias, muscle weakness, and fatigue.

A potassium level of 3.4 mEq/L is below normal, so the nurse should notify the physician before administering furosemide to prevent worsening hypokalemia.

Explanation of Why the Other Options Are Incorrect

B. 4.1 mEq/L

This level is within the normal range. While furosemide can still lower potassium, a physician’s notification is not necessary at this value before administration.

C. 4.5 mEq/L

This level is also within normal limits and does not indicate hypokalemia. There is no need to notify the physician before giving furosemide.

D. 5.2 mEq/L

This value is slightly above the normal range (normal max is 5.0 mEq/L).

A level of 5.2 mEq/L is more concerning for hyperkalemia, but furosemide can help lower potassium in such cases. There is no need to hold the medication or notify the physician.

Summary

The minimum potassium level before administering furosemide without notifying the physician is 3.5 mEq/L. Since 3.4 mEq/L is below this threshold, the nurse should hold the medication and notify the physician to prevent worsening hypokalemia and possible cardiac complications.

Correct Answer A: Decreased respiratory rate

Explanation of the Correct Answer:

Respiratory acidosis occurs when carbon dioxide (CO₂) accumulates in the blood, leading to a decrease in blood pH. This happens due to hypoventilation, where the lungs do not effectively remove CO₂. A decreased respiratory rate results in CO₂ retention, making the blood more acidic

Causes of hypoventilation that can lead to respiratory acidosis include:

Respiratory depression (due to opioids, sedatives, or neurological disorders)

Chronic obstructive pulmonary disease (COPD)

Airway obstruction

Neuromuscular disorders (such as myasthenia gravis or Guillain-Barré syndrome)

Chest wall deformities or trauma

Explanation of Incorrect Answers:

Increased respiratory rate (Incorrect)

An increased respiratory rate (hyperventilation) causes excess CO₂ to be expelled, leading to respiratory alkalosis, not acidosis.

Hyperventilation can occur due to anxiety, fever, pain, or hypoxia and results in an increase in blood pH (alkalosis) rather than a decrease.

Diarrhea for several days (Incorrect)

Diarrhea leads to metabolic acidosis, not respiratory acidosis.

This happens because prolonged diarrhea causes loss of bicarbonate (HCO₃⁻), a base that helps maintain normal pH.

Since the issue originates from the gastrointestinal system, it is a metabolic problem, not a respiratory one.

Vomiting or gastric suction (Incorrect)

Vomiting or excessive gastric suction leads to metabolic alkalosis, not respiratory acidosis

This occurs due to the loss of stomach acid (hydrochloric acid or HCl), leading to an increase in blood pH (alkalosis).

Since the problem originates from acid loss rather than CO₂ retention, it is metabolic, not respiratory in nature.

Summary:

​​​​​​​Respiratory acidosis is caused by hypoventilation, leading to CO₂ retention and a decrease in blood pH. The correct answer is A. Decreased respiratory rate because it directly contributes to CO₂ buildup. The other options relate to metabolic disturbances or respiratory alkalosis rather than respiratory acidosis.

The correct answer is option B: The nurse sits on the side of the bed of a dying patient, holding the patient's hand, and crying with the patient.

Why Option B is Correct:

This option reflects compassionate, patient-centered end-of-life care. Providing emotional support is a crucial part of nursing, especially for terminally ill patients who may experience fear, loneliness, or distress as they approach death. Sitting with the patient, holding their hand, and expressing emotions demonstrates empathy, presence, and genuine human connection, which are core principles of palliative care and hospice nursing.

A nurse's presence can be profoundly comforting to a dying patient. It helps affirm their dignity, acknowledges their emotional pain, and reassures them that they are not alone. Crying with the patient, when appropriate, validates their feelings and shows that the nurse genuinely cares about their experience. This aligns with Jean Watson's Theory of Human Caring, which emphasizes the importance of authentic relationships and emotional connections in nursing.

Additionally, this action follows the American Nurses Association's (ANA) Code of Ethics, which encourages providing emotional and psychological support to patients at the end of life.

Why the Other Options Are Incorrect

Option A: To eliminate confusion, the nurse takes care not to speak too much when caring for a comatose patient.

This option is incorrect because hearing is believed to be the last sense to remain intact in dying patients, including those in a coma. Even when a patient is unresponsive, they may still hear and process what is being said around them. Speaking to a comatose patient in a soothing and reassuring manner can provide comfort, reduce anxiety, and maintain dignity. Avoiding conversation altogether may make the patient feel isolated and disregarded.

Option C: The nurse refers to a counselor the daughter of a dying patient who is complaining about the care associated with artificially feeding her father.

While emotional support for family members is important, immediately referring the daughter to a counselor without first addressing her concerns directly is not the best approach. Nurses should initially engage in active listening and provide direct support, explaining the situation and options before referring the family member to another professional. A referral may be necessary later, but the nurse must first establish rapport and provide immediate guidance.

Option D: The nurse tells a dying patient to sit back and relax and performs patient hygiene for the patient because it is easier than having the patient help.

This option is incorrect because encouraging patient autonomy and involvement in their own care is essential for dignity and self-worth, even at the end of life. While some patients may be too weak to participate, assuming they should not help without assessing their ability can lead to disempowerment and emotional distress. The nurse should encourage participation as much as the patient desires and is capable of, rather than making assumptions.

Summary

Option B is correct because it demonstrates compassionate and emotionally supportive nursing care, which is essential in end-of-life situations. Sitting with the patient, holding their hand, and sharing emotions fosters human connection, trust, and comfort, all of which are crucial in palliative care.

The other options are incorrect because:

Option A ignores the fact that comatose patients may still hear and benefit from verbal communication.

Option C bypasses the nurse’s role in directly supporting the family before referring them to a counselor.

Option D disregards the patient’s potential ability and desire to participate in their own care, which can impact their dignity.

Ultimately, compassion, presence, and emotional connection are fundamental aspects of quality end-of-life nursing care.

The correct answer is C: Writing the client's initials on the student care plan.

Explanation of the Correct Answer:

Writing the client's initials on a student care plan violates confidentiality because it can still be considered identifiable information. According to HIPAA (Health Insurance Portability and Accountability Act) guidelines, even partial identifiers like initials can pose a risk of breaching patient privacy, especially if combined with other details. Student care plans should use de-identified information to protect patient confidentiality.

Explanation of Incorrect Options:

Discussing the client's medications with the clinical instructor – This is not a violation of confidentiality because clinical instructors are part of the healthcare team responsible for overseeing the student’s learning and patient care. This discussion is within the scope of appropriate educational collaboration.

Collaborating with the patient care technician for hygiene care – This is appropriate because patient care technicians (PCTs) are involved in direct patient care and are authorized to receive relevant information necessary to perform their duties. Sharing information related to hygiene care within the healthcare team does not breach confidentiality.

Providing a detailed SBAR report to the primary nurse – The SBAR (Situation, Background, Assessment, Recommendation) report is a standardized communication tool used among healthcare professionals to ensure safe and effective handoffs. Since the primary nurse is directly involved in the patient's care, this is an appropriate and necessary exchange of information.

Summary:

Writing a client’s initials on a student care plan is a confidentiality violation because even initials can be considered identifiable information. The other actions—discussing medications with an instructor, collaborating with the PCT, and providing an SBAR report—are appropriate and necessary for patient care and learning.

Correct Answer C: Perform the bath in a semi-Fowler's position.

Explanation:

Patients with dyspnea (shortness of breath) may struggle to breathe in a fully supine position. Keeping them in a semi-Fowler's position (head of bed elevated 30-45 degrees):

Promotes lung expansion

Reduces respiratory effort

Improves comfort during the bath

Why the Other Options Are Incorrect:

A) Avoid bathing this patient until they are stable.

Bathing is part of basic hygiene and should not be completely avoided unless the patient is in severe respiratory distress.

Instead, modify the approach to minimize discomfort.

B)Only bathe the perineal area.

While a partial bed bath can be done to conserve energy, hygiene should not be neglected.

Patients with dyspnea may still benefit from a full but modified bath, focusing on comfort and avoiding excessive exertion.

D) Delegate the task to the assistive personnel.

While bathing can be delegated, the nurse should assess the patient first and ensure proper positioning.

If the patient has severe dyspnea, the nurse should monitor their response during bathing to prevent respiratory distress.

Key Takeaway:

​​​​​​​Bathing a dyspneic patient should be done in a semi-Fowler's position to support breathing while ensuring hygiene and comfort

The correct answer is: A sign of infection

Explanation for the correct answer:

A sign of infection:

Cloudy dialysate after peritoneal dialysis is an early and classic sign of peritonitis, a potentially serious infection of the peritoneal cavity. This cloudiness results from white blood cells, bacteria, or protein present in the fluid due to inflammation or infection. The nurse should notify the provider immediately, obtain a sample of the effluent for culture, and anticipate starting antibiotics.

Why the other options are wrong:

The normal appearance of dialysate: Incorrect. Normal dialysate should be clear and straw-colored, similar to plasma. Cloudiness is never considered a normal finding and requires prompt investigation.

A sign of vascular access occlusion: Incorrect. Peritoneal dialysis uses the peritoneal cavity, not vascular access. Vascular occlusion is a concern in hemodialysis, not peritoneal dialysis.

 A sign of possible bowel perforation: Incorrect. Bowel perforation may cause the dialysate to appear brown or fecal-contaminated, not just cloudy. Additional symptoms would likely include severe abdominal pain, fever, and rigidity.

Summary:

Cloudy dialysate in a client receiving peritoneal dialysis is not normal and is typically a sign of infection, most commonly peritonitis. The nurse should report the finding, collect a specimen for culture, and prepare for prompt treatment.

Correct Answer C: Self-Esteem Disturbance

Explanation of the Correct Answer:

The individual expresses feelings of dissatisfaction with achievements and persistent low self-worth, which are key indicators of self-esteem disturbance.

The statement "nothing I achieve makes me feel good about myself" suggests an inability to recognize personal success, a hallmark of low self-esteem.

The history of childhood sexual abuse by her father likely contributed to deep-seated negative self-perceptions, reinforcing feelings of unworthiness, self-doubt, and internalized shame.

Her anger toward her father for making her feel “like I'm no good” further supports the presence of self-esteem issues rooted in past trauma.

Explanation of Incorrect Answers:

A: Personal Identity Disturbance

Incorrect because personal identity disturbance typically involves confusion about one’s sense of self, values, or life direction.

This individual does not indicate confusion about who she is as a person but rather struggles with feeling inadequate despite her accomplishments.

There is no mention of identity fragmentation, dissociation, or uncertainty about her role in life.

B: Body Image Disturbance

Incorrect because body image disturbance involves distorted perception of physical appearance or dissatisfaction with one’s body.

The patient’s distress is related to her emotional self-worth, not her physical body.

​​​​​​​There is no indication that she has issues with how she views or feels about her physical appearance.

D: Altered Role Performance

Incorrect because altered role performance refers to difficulty fulfilling expected roles in life (such as being a worker, parent, or spouse).

While the patient may have difficulties in personal and professional roles, her primary issue is not about role fulfillment but about deep-seated self-worth issues stemming from past trauma.

​​​​​​​There is no mention of struggles with role expectations or responsibilities.

Summary:

​​​​​​​This individual is experiencing self-esteem disturbance, as she feels inadequate and unworthy despite professional success. Her history of sexual abuse has contributed to feelings of self-hate and dissatisfaction, which are common in individuals with low self-esteem. Counseling should focus on trauma processing, self-acceptance, and fostering a healthier self-concept.

Correct Answer  A: Slow or stop the infusion; monitor vital signs, notify the health care provider, place the patient in an upright position with feet dependent.

Explanation:

The patient is exhibiting signs of transfusion-associated circulatory overload (TACO), a condition caused by excessive fluid volume from the transfusion leading to pulmonary edema.

Priority Nursing Actions:

Slow or stop the infusion to prevent further fluid overload.

Monitor vital signs to assess for worsening respiratory distress.

Notify the health care provider for further orders (e.g., diuretics like furosemide).

Position the patient upright with feet dependent to promote better lung expansion and reduce venous return to the heart, helping with symptom relief.

Why the Other Options Are Incorrect:

B) Stop the transfusion immediately and keep the vein open with normal saline, notify the health care provider stat, administer antihistamine parenterally as needed :This describes an allergic (anaphylactic) reaction rather than TACO.

Anaphylactic reactions usually present with rash, wheezing, hypotension, not pulmonary edema.

Antihistamines are not the priority for fluid overload.

C) Stop the transfusion immediately and keep the vein open with normal saline, notify the health care provider, and treat symptoms.

Correct for a hemolytic reaction, but does not include positioning the patient to help relieve respiratory distress.

Keeping the vein open with normal saline may worsen fluid overload.

D) Stop the infusion immediately, obtain a culture of the patient's blood, monitor vital signs, notify the health care provider, administer antibiotics stat: Sepsis is suspected with fever, chills, and hypotension, not dyspnea and pulmonary edema.

Blood cultures and antibiotics are unnecessary in TACO.

Final Summary:

The priority action for TACO is to slow or stop the transfusion, monitor the patient, notify the provider, and position the patient upright with feet dependent to reduce pulmonary congestion. Option A is the correct answer.

Correct Answer A: It ensures that the patient understands the procedure, risks, benefits, and alternatives before making a decision.

Explanation of the Correct Answer:

Informed consent is a legal and ethical requirement that ensures the patient has a clear understanding of the surgical procedure before agreeing to it. It is essential for patient autonomy, medical ethics, and legal protection.

Key Reasons for Informed Consent:

Patient Autonomy: The patient has the right to make an informed decision about their own body and medical care.

Full Disclosure: The surgeon must explain the nature of the procedure, risks, benefits, potential complications, and alternative treatments so the patient can make an educated choice.

Legal Protection: Informed consent provides legal documentation that the patient agreed to the procedure with full knowledge of the possible outcomes.

Ethical Responsibility: Healthcare providers must respect patient rights by ensuring they fully understand their options before undergoing surgery.

Explanation of Incorrect Answers:

Option B:

It is a routine hospital policy but does not have any legal or ethical significance.

This is incorrect because informed consent is not just a hospital policy—it is a legal and ethical obligation. If a patient undergoes surgery without consent (except in emergencies), it can be considered medical malpractice or battery.

Option C:

It prevents the patient from suing the hospital if complications arise during surgery.

Informed consent does not eliminate a patient’s right to legal action. If a healthcare provider is negligent or fails to meet the standard of care, the patient can still file a malpractice lawsuit.

Option D:

It is only necessary for high-risk surgeries but not required for minor procedures.

This is incorrect because informed consent is required for all invasive procedures, including minor surgeries. While some low-risk treatments may require only verbal consent, any surgical intervention requires written informed consent.

Summary:

Informed consent is a critical legal and ethical process that ensures the patient understands the surgery, its risks, benefits, and alternatives. It respects patient autonomy, protects healthcare providers legally, and upholds medical ethics. It is required for all surgical procedures, regardless of complexity.
