Nursing Elites

1. The cells of a normal individual can replicate in a specified rate. If the rate of replication becomes uncontrollable, which of the following is lacking from the patient?

• A. Apoptosis
• B. Contact inhibition
• C. Stable cells
• D. Labile cells

Correct answer: B

Rationale: Contact inhibition is a regulatory mechanism that prevents cells from proliferating once they reach a certain density. Normally, when cells grow and touch each other (such as in a monolayer), they stop dividing, maintaining tissue integrity and structure. When contact inhibition is lacking, as in many cancerous cells, cells continue to grow and divide uncontrollably, leading to tumor formation. This loss of regulation is a hallmark of cancerous growth.

2. The clinic nurse is caring for a patient whose grandmother and sister have both had breast cancer. She requested a screening test to determine her risk of developing breast cancer and it has come back positive. The patient asks you what she can do to help prevent breast cancer from occurring. What would be your best response?

• A. Research has shown that eating a healthy diet can provide all the protection you need against breast cancer.
• B. Research has shown that taking the drug tamoxifen can reduce your chance of breast cancer.
• C. Research has shown that exercising at least 30 minutes every day can reduce your chance of breast cancer.
• D. Research has shown that there is little you can do to reduce your risk of breast cancer if you have a genetic predisposition.

Correct answer: B

Rationale: Tamoxifen is a selective estrogen receptor modulator (SERM) that has been shown to significantly reduce the risk of developing breast cancer in women who are at high risk, particularly those with a family history of the disease or a positive genetic test for BRCA mutations. Large-scale studies have demonstrated that tamoxifen can reduce the incidence of breast cancer by up to 50% in high-risk women. It works by blocking estrogen receptors in breast tissue, which helps prevent the development of estrogen receptor-positive breast cancers.

3. A nurse is providing care to a patient who has just received a diagnosis of acute myeloid leukemia (AML). What is the priority nursing diagnosis for this patient?

• A. Risk for bleeding
• B. Risk for infection
• C. Impaired gas exchange
• D. Imbalanced nutrition

Correct answer: B

Rationale: Risk for infection is a high priority due to the patient's compromised immune system from AML.

4. The nurse is caring for a client following radical neck dissection and creation of a tracheostomy. Which assessment finding would indicate an immediate need for intervention?

• A. Frequent swallowing
• B. Presence of mucous membranes
• C. Bubbling in the water-seal chamber
• D. Inspiratory stridor

Correct answer: D

Rationale: Inspiratory stridor is the correct answer as it suggests airway obstruction, a critical issue requiring immediate intervention. Frequent swallowing (choice A) is a common postoperative finding and does not indicate an immediate need for intervention. The presence of mucous membranes (choice B) is a normal finding and does not require immediate intervention. Bubbling in the water-seal chamber (choice C) of a chest tube drainage system is an expected finding and indicates proper functioning of the system, not an immediate need for intervention.

5. The nurse manager is teaching the nursing staff about signs and symptoms related to hypercalcemia in a client with metastatic prostate cancer and tells the staff that which is a late sign of this oncological emergency?

• A. Headache
• B. Dysphagia
• C. Constipation
• D. Electrocardiographic changes

Correct answer: D

Rationale: The correct answer is D, Electrocardiographic changes. In clients with metastatic prostate cancer, hypercalcemia can lead to various signs and symptoms. Electrocardiographic changes are considered a late sign of hypercalcemia, indicating severe electrolyte imbalance. Headache (choice A), dysphagia (choice B), and constipation (choice C) are earlier signs of hypercalcemia and may precede the development of more severe symptoms like electrocardiographic changes.
