Nursing Elites

1. What are the major electrolytes in the extracellular fluid?

• A. potassium and chloride
• B. potassium and phosphate
• C. sodium and chloride
• D. sodium and phosphate

Correct answer: C

Rationale: The correct answer is sodium and chloride. These two electrolytes are the major components of extracellular fluid. Potassium and phosphate (Choice B) are not the major electrolytes in the extracellular fluid. Potassium is primarily an intracellular ion, and phosphate is more abundant in the intracellular fluid and bones. Sodium and phosphate (Choice D) are also not the major electrolytes in the extracellular fluid. Chloride plays a crucial role in maintaining electrolyte balance and is predominantly found in extracellular fluid alongside sodium.

2. The nurse is checking laboratory values on a patient who has crackling rales in the lower lobes, 2+ pitting edema, and dyspnea with minimal exertion. Which of the following laboratory values does the nurse expect to be abnormal?

• A. Potassium.
• B. B-type natriuretic peptide (BNP).
• C. C-reactive protein (CRP).
• D. Platelets.

Correct answer: B

Rationale: The client's symptoms suggest heart failure. BNP is a neurohormone released from the ventricles due to increased pressure and stretch, as seen in heart failure. A BNP level greater than 51 pg/mL is often associated with mild heart failure, with higher levels indicating more severe heart failure. Potassium levels are not typically affected by heart failure. CRP is an inflammation indicator used to predict coronary artery disease risk, not directly related to heart failure in this case. The client's symptoms do not suggest bleeding or clotting abnormalities associated with platelet count issues, making platelets an unlikely abnormal value.

3. A one-month-old infant in the neonatal intensive care unit is dying. The parents request that the nurse administer an opioid analgesic to their infant, who is crying weakly. The infant's heart rate is 68 beats per minute, and the respiratory rate is 18 breaths per minute. The infant is on room air, and the oxygen saturation is 92%. The nurse's response is based on which of the following principles?

• A. Providing analgesia during the last days and hours is an ethically appropriate nursing action.
• B. Withholding the opioid analgesia during the last days and hours is an ethical duty because administering it would represent assisted suicide.
• C. Administering analgesia during the last days and hours is the parents' ethical decision.
• D. Withholding the opioid analgesia is clinically appropriate because it will hasten the infant's death.

Correct answer: A

Rationale: All patients, regardless of age, have the right to die with dignity and be free from pain. In this case, the parents' request for an opioid analgesic to relieve the child's distress aligns with the principles of palliative care and ensuring comfort. Assisted suicide involves a conscious decision by the individual, which is not applicable to a 1-month-old infant. Both the nurse and the parents have an ethical duty to ensure the infant's comfort and well-being. Withholding opioid analgesia solely to hasten death is not appropriate, as providing pain relief is a crucial aspect of end-of-life care. Opioids can be administered to dying patients at any age to alleviate suffering without the intention of hastening death. Therefore, providing analgesia during the last days and hours is an ethically appropriate nursing action. Choices B, C, and D are incorrect because the decision to administer analgesia in this scenario is based on the best interest and comfort of the infant, not concerns about assisted suicide or hastening death. The ethical consideration is to provide compassionate care and alleviate suffering.

4. Which system is primarily affected by tuberculosis (Mycobacterium)?

• A. stomach (GI)
• B. heart (cardiac)
• C. lungs (respiratory)
• D. skin (integumentary)

Correct answer: C

Rationale: Tuberculosis, caused by Mycobacterium tuberculosis, primarily affects the respiratory system. This aerobic bacillus thrives in highly oxygenated body sites, such as the lungs, growing ends of bones, and the brain. The bacillus is airborne, making the lungs a common site for infection. Choices A, B, and D are incorrect as tuberculosis predominantly impacts the respiratory system and rarely involves the stomach, heart, or skin.

5. A client with stress incontinence should be advised:

• A. to avoid relying solely on absorbent undergarments.
• B. that Kegel exercises might help.
• C. that effective surgical treatments are available.
• D. that behavioral therapy can be beneficial.

Correct answer: B

Rationale: Kegel exercises, which involve tightening and releasing the pelvic floor muscles, can be beneficial for stress incontinence by strengthening the muscles that control urination. Choice A is incorrect as it is important for the client to know that absorbent undergarments can be used as a temporary solution but do not address the underlying issue. Choice C is incorrect as while surgical treatments are available, they are usually considered when conservative treatments like exercises and behavioral therapy have not been successful. Choice D is incorrect as behavioral therapy can be beneficial in managing stress incontinence through lifestyle and dietary modifications, bladder training, and more, contrary to the statement that it is ineffective.
