which his gastric content and fluid were removed: pH 7.55, PCO2 50, HCO3 35. What acidbase
imbalance is most likely in this patient? - Correct Answers Metabolic alkalosis, compensating
A 50-year-old male visits the cardiologist for an EKG. Results indicate that he has no
PR interval and a variable QRS rate with rhythm irregularity. Which of the following is
the most likely diagnosis to be recorded on the chart? - Correct Answers Atrial fibrillation
A 65-year-old male is transported to the ER for chest pain. An electrocardiogram
reveals a prolonged QRS interval. What is the nurse monitoring when the nurse
observes the QRS complex on the electrocardiogram? The QRS complex reflects: - Correct
Answers Ventricular activity
Which is one of the acid/base conditions that would cause the nurse to monitor for
hyperkalemia? - Correct Answers metabolic acidosis
A 20-year-old male is in acute pain with restlessness and anxiety. An arterial blood gas
reveals decreased carbon dioxide (CO2) levels. Which of the following does the nurse
suspect is the most likely cause? - Correct Answers hyperventilation
,A 24-year-old female presents with excessive menstrual bleeding. The physician identified
endometrial changes that are due to hormonal imbalances. These cellular changes would be
referred to as: - Correct Answers Pathologic hyperplasia
A 34-year-old was diagnosed with malignant tumor (cancer). The nurse teaches the patient
about malignant cells. Which of the following is most appropriate explanation when describing
malignant cells? - Correct Answers Malignant cells are dysplastic cells and are irreversible
A characteristic of a malignant tumor includes that it: - Correct Answers can spread far from the
tissue of origin
A 25-year-old male develops cancer of the breast glandular tissue. What type of cancer does he
have? - Correct Answers adenocarcinoma
When planning care for a cardiac patient, the nurse knows that in response to an increased
workload, cardiac myocardial cells will: - Correct Answers Increase in size
The term apoptosis is appropriately defined as: - Correct Answers programmed cell death
A report comes back indicating that muscular atrophy has occurred. A nurse recalls that
muscular atrophy involves a decrease in muscle cell - Correct Answers size
A nursing student is studying about cancer and the associated risks for cancer. The instructor
knows the student understands cancer when which of the following are associated risks for
cancer? - Correct Answers -Epstein-Barr virus (EBV)
,-hepatitis C virus (HCV)
-hepatitis B virus (HBV)
-human papillomavirus (HPV)
A primary care provider is attempting to diagnose cancer and is looking for a tumor marker.
Which of the following could be a possible marker? - Correct Answers Enzymes
A 30-year-old homeless was seen in the emergency room with productive cough of bloodtinged
sputum. His chest x-ray showed granulomatous disease. Upon further questioning, he
was found to have had tuberculosis (TB) in distant past. TB infections are likely to result in
which of the following forms of necrosis? - Correct Answers caseous
When discussing body fluid, it is correct to state that: - Correct Answers Two-thirds of the body's
water is intracellular.
Rationale: One-third is extracellular. There are two components of the extracellular
compartment: interstitial and intravascular. Total body water is about 60% of body weight.
Which of the following statements is TRUE? When discussing body fluid movement, it is correct
to state that:
A) Potassium is the most abundant extracellular fluid (ECF) ion.
B) Sodium maintains the osmotic balance of the intracellular fluid (ICF) space.
C) Water moves freely across membranes.
D) Aquaporins block water movement across the membrane. - Correct Answers C) Water moves
freely across the capillary or cell membrane.
, Rationale: Aquaporins are a family of water channel proteins that provide permeability to water
at the capillary membrane. Sodium is the major ECF cation, and potassium is the major ICF
cation; this is due to the sodium-potassium pump.
When discussing aldosterone, it is correct to state that: - Correct Answers It is a hormone that is
secreted when sodium levels are depressed.
Rationale: Aldosterone is a minerocorticoid secreted from the adrenal gland that is located on
the kidney. Aldosterone is secreted when potassium is increased or sodium is decreased.
Therefore, it makes sense that aldosterone increases sodium reabsorption to increase a
depleted supply. It also increases potassium secretion.
When discussing hyperchloremia (elevated serum chlorine), it is correct to state that it: - Correct
Answers Is a result of an underlying disorder.
Rationale: Hyperchloremia is usually related to an underlying disorder, and therefore, treatment
is centered on the underlying disorder. It usually occurs with an increase in sodium and a deficit
of bicarbonate. There are normally no specific symptoms associated with this syndrome.
When discussing hyponatremia (low serum sodium), it is correct to state that it is generally: -
Correct Answers An outcome of serious burns, vomiting, or diarrhea.
Rationale: Hyponatremia occurs when the serum sodium drops below 135 mEq/L. It can occur
due to burns, vomiting, diarrhea, or gastrointestinal suctioning. It can also occur with an
increase in TBW. Inadequate sodium intake can cause hyponatremia, but it is uncommon.
Which of the following is a TRUE statement regarding hyperkalemia (elevated serum
potassium)? - Correct Answers It often occurs in acidosis.
